I don't think so. The dog bones and lower links would be far less parallel as the post war fork is 1 inch longer between the links, plus that is a prewar friction damper wing nut not a bakelite knob and no little brass spacers between the forks and the links.

The lower lugs are strange in relationship to the brake hub. It looks like a post war brake hub connection, where you have the location on the brake plate.

I think it is because that is not a Vincent brake drum as we know it so some adaptation has been made.

Also there are quite a few late series B's with Girdraulics,

Also looks like a series A tank not the type used on the python machines? Should be smaller capacity and have John Bull knee rubbers? Also the engine is not one supplied to Vincent. The carb body should be tiltled on its side as it would have had the larger magdyno that meant the carb was too tall fitted in its usual upright position. Interesting project for sure but very much a bitsa.

Yep that’s the one. This is the one on our model p
Lovely. Similar to the carb on my TPS. Are you sure the engine type was not supplied to Vincent?

It looks the same as the club's DPS and a bronze semi radial head ties in with 1934.

HI Nulli. Yep you're right it is the same type of engine used and supplied for the (DPS) python sports which was the ulster engine with the radial head. The DP python simply had the engine used in the Rudge sports special which had the non radial and non bronze head, and is the rarer of the two models with only 46 or so made. I only know that the engine on the auction bike isn't one supplied to Vincent as I asked Simon at the VOC to check the factory records and he confirmed that the frame was a python sports frame but the engine number did not appear to be one that was supplied to Vincent. Although as you say is the same type of engine. Still it is an interesting and very rare bike that would make a great restoration project.

In the auction details it does suggest that some parts of the Vincent may have been swapped with the Rudge in the sale (the one with a crude looking swinging arm frame conversion). May be the buyer needs to buy both bikes or do a deal to swap parts with the new owner of the Rudge, assuming it sells.

The engine for the HRD looks to be on the Rudge after your recent posts.
