There are quite a few knowledgable guys on this facebook group: https://www.facebook.com/groups/444624876468800 Only way to join is by answering ALL entry questions and agreeing to group rules.

Now that the workshop has come up to a manageable temperature, I've been back to check actual dims, both rims are within a gnat's toozle of 22 5/8" o/d. The ancient rim is 1 13/16" wide, the new one is 2" wide, so apologies for wildly inaccurate guestimations! I also found a newer rim that I got from the VMCC supposedly for 26 x 2, that also measures 22 5/8" x 1 13/16", but the welded joint leaves a lot to be desired.
It looks like I may end up ditching the old rims, reworking/improving the VMCC rim (so I can get it nickel plated for the stirrup brake) using the new slightly wider rim on the rear, and as you say, sticking with 2" tyres (my other 1912 little Enfield twin has 2" tyres, but they are the old delivery push bike tyres, on wired on rims). No doubt fitted in the days when BE sizes were even scarcer than today.....

2" tyres at 40+ psi are no joke - I know from riding the other Enfield! But great fun until the pain barrier is reached. 

Still seems odd that same o/d rims fit different section tyres........

Hope folks don't mind me jumping in on this one....I'm entering into my 1st foray with BE tyres.
I have a bike from 1912, which is a factory prototype/development bike, came to me without any rims.
The front forks will only pass a 2" BE tyre, the rear will comfortably accommodate a 2.5" tyre.
I approached a rim manufacturer in the UK, to check what size rims were needed, and he came back with same diameter rims for different size tyres (although different profiles I believe).
When I suggested this didn't appear to add up, could he expand, there was a stoney silence......
I can see how a 26 x 2 tyre needs a 22" rim, but how can a 26 x 2.5 also need a 22" rim?
What happens to the extra 0.5" (x2)?

No problem, glad to have been able to help!
Wouldn't have known what it was without the seller identifying it.

I've got both a 350 and 500 Levis, and neither of these bikes in the photos is a Levis.
Levis used a single front frame tube as already mentioned, but it connects to engine plates at the TOP of the crankcase.
In the top photo the front frame tube can be seen continueing to a much lower level.
The exhaust ports do project on a Levis, but not like in the top photo, also the pipes leave the head fairly horizontally, before curving down, and the bend projects in front of the frame tube when viewed side on. None of these features in the top photo.
The petrol tank is the wrong shape, and the blurry maker's transfer is too far forwards.
Hope this helps 

You could put me down as another potential customer!
My wife and I have just bought a 1927 Ladies Model 201a Royal Enfield in need of tlc.
The mrs has got fed up of sitting on the sidelines whilst I tootle off on old bike runs (her Yam Virago doesn't quite fit in a pre 1930 run).
The 2 speed gear is not of interest (but is definitely 225cc 2 stroke variant), as by '26 a 3 speed conventional gearbox had replaced the 2 chain/2 clutch set up (my 1912 350cc v Enfield/motosacoche has one of those, but subtly different to the 2 stroke version).
Once you've decided what bits are not later model A, drop me a pm, I may be able to help with identification.
Going down to Devon to pick up the Ladies model this weekend.
Cheers Keith

Definitely a 4 speed hand change box, fitted to New Hudson, Calthorpe and OK Supreme.
You can see a Calthorpe fitted with one at: https://www.youtube.com/watch?v=T3_XfC19FSc

That email doesn't come up when I try it, must be something to do with being 1/2 a world away.
I've dropped the guy an email just in case.
Thanks for that.
