Ok so there has been quite a discussion about numbering of Royal Enfield frames . Here is another one . Recently Tom mentioned in the forum that some frames have a date stamped on the headstock on the opposite side of the serial number (timing side) . When he was here last weekend this subject was brought up again . We checked a couple frames . What I have been calling a Fury fr. 15771 eng. 3327 (big head , 1 1/2" intake , 2" exhaust valve , Royal Enfield badged timing cover , slim primary cover , racing mag. no provision for headlight mount on fork covers )has the numbers 11-58 P . Frame 8091 that has been dated as a 1959 Constellation has B 4-59 . Frame 7897 dated as 1958 Constellation has B 8-58 . Crusader 250 frame 11158 also has numbers on it but I can not tell for sure what they are .
Any ideas who put these numbers on ? Done at the factory or by a certain dealer ? Done for importing ?
Another stamping that I have found is M&B and sometimes just the & mark . John

Just to add to what John posted. One other bike on e-bay a while back that looked like a chief was stamped 8828 and 1-59, the engine was stamped pc50021.

If Royal Enfield stamped them they weren't consistant. I have 4 twin frames that date from late 1957 to early 1958 (Indian) and 1 that is from a 1963 (dated by engine number) Interceptor but its frame number is unusual for a 63 Interceptor compared to the Burton Bike Bits register. None of the six frames have any stamp on the right side. They just have the forging numbers 4759 with the delta sign underneath (triangle). These are raised symbols, definitely not stamped.

Redditch may have stamped them to designate a contract assignment. Gordon May borrowed records from Major Walker Smith's son who was the secretary for Royal Enfield in that time frame. A person might send him an e-mail and enquire about what he might have picked up while jumbling through those records.

Okay, one more time. An old '06 post here had someone from Dearborn, Michigan attempting to ID his machine with frame #9212 also stamped R 10-60.None of my frames have this extra dating.

Just out of curiosity, are the stamped numbers that you've seen on the right side the same type and size of characters that are stamped on the left (frame number)? That might be a clue. I've got stamps that are New Times Roman character type font and some that are more of an Arial type character font and in sized in 1/4", 1/8", 3/32", & 1/16". I've also seen other types that were more of a special nature to try to prevent fraudulent stamping of VIN numbers.

My frames all have a 1/4" New Times Roman type number stamp for the frame numbers.

The stampings are smaller but consistent from what I have seen.

The date stamping is approx 1/8" numbers and the letter designation (if that is what it is) is slightly larger at 3/16" . As on the Fury 11 - 58 and below that a F . As well Yes there is a casting number 4759 with the triangle sign . John

Hi! & interesting string!!!

I have never been able to exactly figure out the serial # issue... I think I may have mentioned in a previous post about title issues that I have a title for a frame which was sold as a complete bike (new) in 1957 & transfered again in 1964 ( to me )bearing the vin #( on the title) & frame # of 4759 ( = part # casting !!!!)... even after sandblasting the frame, no other numbers are apparent on either side... For this reason I have not built a bike using this frame or title! One cannot help but wonder just how many bikes were mis-registered back in the day. I have been told that an acid dip of a clean frame will reveal any original numbers that may have been removed or altered. Is it possible that the Indian/RE twins were sent to the US sans serial numbers to be added by the distributor? Or did they just not worry about it since engine numbers were used for ID back then? Any ideas/info out there?

The REOC/UK has the record of frame numbers from Royal Enfield but I have no idea where they got them from. If I had to guess I would figure it was from a member of the original Smith family who were founders of the marque. When manufacture was terminated in 1970 the ownership was transfered several times until Mick Page bought up what was left. Mick (Burton's Bike Bits) did mention that he purchased the stuff from Aerco Jig & Tool in 1981 on the Burton's Bike Bits web-site.

Someone should be still living that can shed some light on this.
