Thank you very much!!
I dont think i would have found out this by my self.
This seems to be a rather obscure little bike, very little to find online.
I found a just a couple of pictures of the same bike.

Knowing the name of the bike, i have asked our national registration archive for information, and  are awaiting an answer.

Does the framenumber tell anything? Is there any lists of numbers that includes Montgomery's?

I have not found much info about the factory or production-numbers either, i guess it was a rather small factory?

Maybe this could make the missing parts easier to get hold of, since they bought most of them?
Like wheels (British hub co??), gearbox (Albion?), Jap-engine, Dunlop drilastic(?) saddle....

Please let me know if any other parts are recognized as standard parts that could come from other bikes or makers?

I guess the hardest part will be the gastank, or could this also have been bought from another maker?

Anyway, thanks a lot for the info so far. It helped me a lot.

Greetings from Norway. Per.

Metric measurements make sense, because the frame is French, from a 1904-5 Alcyon. This model was usually seen with a Buchet motor - it appears there was a lightweight version using a Swiss Zedel motor, but this used a slightly different central lug.

The black-and-white illustration shows the Alcyon-Buchet. I had trouble finding drawings or photos that showed the frame details to compare with the surviving frame, but I did find some photos of a "restored" Alcyon "racer", fitted with an OHV Buchet motor. I strongly suspect this machine is not what it pretends to be, and that the frame is the standard Alcyon frame with the lower tank rail removed to make room for the tall OHV engine. I could be wrong; perhaps it is real. Anyway, if you study the photos I think you'll find - lower tank rail detail apart - that the frame is the same as the one under discussion here.

Yes it could be a small v-twin, or equally a single. I haven't looked at Sarolea, but I was thinking of Fafnir. Can you measure the width of the lugs that take the engine plates? Fafnir motors used very narrow lugs.

Against a continental id is that some of the frame lugs are quite heavy, particularly the one at the lower end of the steering head. European stuff was typically quite elegant. Brown Bros was a good thought, but I can't see the funny bottom bracket lug anywhere in the Brown range.

Just a thought. As to me it looks quite long could it of fitted a small V twin ? Looking at some photos of a Sarolea that looks close though never seen one in the flesh and can't see lower fram engine mount lugs.

Here's an earlier discussion on the hexagON tap: http://classicmotorcycleforum.com/index.php?topic=5335.msg22597#msg22597

A google search for "ewarts plunger tap" brings up lots of photos, like the one below.

Both tap types were widely used, and there are lots of variants, and lots of modern reproductions.
