Hello All! New to REs and wanting to know a direction. I have what I believe to be a Interceptor frame and swing arm and tank, forks ,triple tree, wheels with front and rear brake plates but no drive sprocket assembly. Was considering sourcing the other parts overtime and doing a restore. But I don't see the motor and trans come up on CL or eBay very often. And not even sure if its practical. But then I think none of my past restores have been practical. Soooooo. Seeing as the redditch REs seem to be more cloistered than all the other BritBikes. Are these parts sourcable in a reasonable time??? 2 years? 3 or more? Thanks in advance. Sol.

Hi Sol. Welcome to the "club" of Interceptor owners. It's hard to assess your project without photos. Read the How To thread about posting images in the Hot Links Bulletin Board. Postimages.org is an easy to use website for Hosting images.
Besides this forum you should visit the Yahoo RE Interceptor Group.
https://groups.yahoo.com/neo/groups/RE_Interceptor/conversations/messages/24018
And the Ozemate site - http://www.ozemate.com/interceptor/
Parts are available from Hitchcocks - http://accessories.hitchcocksmotorcycles.com/
Burton's - https://burtonbikebits.net/
and Baxter's in the US - https://www.baxtercycle.com/parts/
Make a list of parts you need using the parts lists on Hitchcock's site. Estimate the cost. Hitchcock's has many used parts and a phone call may even turn up a whole engine. Use the forums to locate the hard to find parts.
Weigh the options of building a "rider" or a complete restoration against the cost of parts. After visiting Hitchcock's site you may be surprised at what is available.
Post some photos and we can give more specific advise.
Good luck and looking forward to following your project.
Al - owner '67 1A Interceptor

Sol, the serial number stamped into the headstock will tell what your frame is. Probably right down to date of dispatch from the factory, and destination dealer. Generally, the number will be on the left side (left, as you are seated on the motorcycle.) but there are exceptions. Just look for numbers STAMPED IN, any letters too, and ignore numbers cast in. Post the numbers or alpha-numeric here and we can tell what we know. If you prefer to go straight to the well for facts, go to royalenfields.com and look for the blurb on the right about contacting the Royal Enfield Owners Club chairman.

There were fewer than 200 700cc Interceptor built, and 4000 of the 750's.

Having my doubts now of it being a interceptor. After doing some research and comparisons of other frames. The biggest con against the frame is no support bracket from the top horizontal tube to the down tube in the front. And the obvious fact that there are Only 3 stamped numbers in the headstock ( 679). Also the top of the triple tree is rather plain . The tank though has 2 peacocks and is chrome, with the remainder of a factory red panel in the center that someone removed all except the small portion that the seat obscured. The fenders are factory chrome,least I think so..The rear tail light is the later Lucas fitted to Triumphs and REs,with pointy protrusion in the center/ lower. I guess its possibly a distant past hodge podge bastard enfield parts. Or a Connie or Meteor. Regardless going to give it sometime and attention to parts sourcing. Maybe another enfield twin will come along to cannabalize here.Any thoughts are appreciated. Thanks in advance Sol

Sorry to take so long. You have a 1968 Series 1A Interceptor, serial number 679. Congratulations! The engine in this bike was IA 679. The chrome "peanut" tanks like yours have always been in demand for custom bikes, so they are scarce. You have fenders, tail light, presumably the licence plate bracket and the sub-frame that joins the above and the seat. Your bike left the factory in Upper Westwood in April 1968, shipped to Cooper Motors in LA. Does the front wheel have a pair of perforated aluminum discs on the hub? They are non-functional but meant to replicate the cooling fins used on Isle of Man racers before drum brakes were replaced with disc.
There were about 1000 1-A's built, and motors come up from time to time. Any postwar Enfield twin motor will fit that frame, and most of the singles of 350cc and larger. Even the Bullet engines from India. Dunno about the new RE 650 twin engine......
What are your plans now?

WOW! All that from 3 numbers. Thanks a lot Chris and Al also. Will probably work towards that goal of restoring it. No it does not have the perforated discs around the drums as I have seen in pics. And since my last post I've noticed that the 68,69,70 models had attached speedo and tach. Unlike early models where they were in a formed top triple tree for mounting them. The lack of a frame brace had me thinking it might be a Connie or Meteor. But I think it must have been removed like a lot of other parts. Will have to acquaint to the world of Enfields. Kinda Stoked now. Thanks again.

The frame brace you mention was on the smaller Crusader series frames (unit 250 engine) and not on the twin frames. Note the top tube on your frame has a lug for the cylinder head steady, and the tabs for the battery back plate point forward, unlike models with a toolbox where the tabs point inwards. If there are tapped holes on the rim of the front hub, they are for the "bacon slicer" discs. If no holes, someone has traded front wheels.

See the online parts book on Hitchcock's website.

Hello again Chris. I do have one question. Are these bikes in 1968 CEI threaded fasteners?

The predominant thread form used in Royal Enfields is BSF, British Standard Fine. You will find BSW Whitworth, and Cycle threads on some of their parts, and BA British Association threads on Smith's instruments and Lucas components. The busiest tools in my shop are thread gauges (followed by magnifiers). To put a very fine point on Cycle threads, in 1939 CEI Cycle Engineers Threads were rationalized and became BSC, British Standard Cycle. Find a good summary of thread forms on the net and print it for your shop. I found such a list a few years ago but the link does not work now.

Out of curiosity, when did Enfield change to BSF?
I have done a fair bit of work on older models, H,J, L, J, G, C, CO & J2.
The vast majority of the threads are 26 tpi, even the large diameter threads on the crankshaft.
