Hi all, I have been restoreing an early 1947 rapide and have for the last three years been trying to find a timing side casing with the pronounced oil ways,
is there any one out there with a spare one, or one they would swap, with a H.R.D. timing side case without the pronounced oil ways, which I currently have, obviously i would be prepared to pay the going rate for the said item, or should i give up the quest, also i would like advice on any upgrades to my rebuild that wouldnt detract form the originality of the early Rapide,
Many thanks in anticipation Paul

The raised oilways timing covers are the preverbial hen's teeth as the item was only fitted to so few of the early bikes and many of those were exported back in the day, that said I am assuming that you have already researched your engine number and validated its place within the components/numbers sequence to ensure you are not a pointless search.

I would suggest you are more likely to find your part if you finish and run the bike with the case you have, once out and about you are more likely to come into contact with 'someone who knows someone' as these days there are many pleas for correct parts only to have a 'correct bike' shortly on the market for an eye watering price. Good that you are prepared to swap out what you have.

Unfortunately I cannot help you, good luck tho'.

Thanks Phil, i dont think there's much chance of finding one, but you got to keep trying, on the search for a round brake switch aswell, wich will be much the same storey i think, i have seen the remanufactured ones but again the price is eye watering, why is it that any thing to do with Vincents is so costly, i am lucky to own one, but we are not all millionaires!!!

"why is it that any thing to do with Vincents is so costly,"
1) Because so many 'experts' have previously imposed their 'know better than the factory' knowledge (not) on the poor unfortunate machine, with consequent wallet emptying correct repair costs.
2) The engines were designed without compromise, so correct repairs are without compromise.
3) So many previous spares were frankly, just useless pieces of expensive metal, so modern spares are made to a standard rather than cost.

Where in Warks are you, I'm not too far from Alcester (shortly), if you need any help PM me, I'll help where I can.
Cheers

Miller 42E switch

I think 3 yeans on eBayUK to find a nice working OEM Miller 42E.

I have seen few since, maybe 2.
Automotive application might be Jowett.

Many other 47 and earlier differences - timing cover, heads, headlamp, taillight, rear stand, fenders, dynamo, clutch cover.......on and on., many more.

Great detailed picture, yes there are a few differences with the eary Rapides, I am however lucky enough to have most of the original parts, i will continue the search, the Jowett application sounds like a good line to persue, thanks for that, cheers!

In the US, but you might try Keith Martin at Big D Cycle in Dallas Texas. He has quite a large collection of original Vincent parts on hand, having acquired several stashes of them.

The Factory made three different kinds of HRD covers. The first one was sand-cast and had large veins, which is the one you are looking for. The second type was sand-cast with smaller veins. The cover was simply cast thicker to minimize the veins. This cover was very heavy. The last cover, which was probably early 1948 was die-cast and had the HRD, but no veins. The Series C Vincent was introduced in December of 1948 and the Factory wanted to introduce the "Vincent" name, rather than "HRD," but this took most of 1949. Many bikes had the HRD logo ground off the timing cover and the valve caps. These bikes are usually referred to as the transition models.

All to say, the early large vein timing cover is the most difficult to find due to the numbers. A friend just bought one and he looked for about a year. They do pop up.

Here’s an obscure one for you. There was a fellow on the VOC forum looking for a A50AS fuel pipe for his B restoration. At the time, I hadn’t noticed the difference. The one on the bottom (square junction) is the “B” version he was referring to, although I’m sure with a lot of components there are no guarantees that they weren’t just fitted with whatever was in the bin at the time. Both these are NOS, which is interesting given the difference in finish.

Hi Cyborg, I have had to go into the workshop to see which type i have, glad to say its the square styled one, as you say i bet theres numerous small detail differences depending on supply at the time of construction.
I think you would have to be a proper rivet counter to notice the difference on a road bike, (no offence to any rivet counters out there, we all have our foibles, mine is sometimes a lack of tact!!!)
