what is it

[mark2]

what is it , I know its a bits and bobs but what

[R]

A straight-on view of the side with oil tank and front brake would be more definite...

Obviously an all alloy T100 engine but it's so long since I've had a Rigid Trumpy I can't tell if It's a Trumpy frame at all? The front engine plates don't look right so possibly isn't Trumpy.

will post more pics , I have the panel tank and the gear box (three speed foot change two bolt fixing ) the engine is wrong but I will use , I think , it has a left hand twist grip and all cables run thro the bars (five of)

Looks like it could be Ariel, but will wait for the pics.
Especially the tank panel, if that is part of it.

I got this for free when I went to buy a James , the person had given up biking and was selling up , some very rare and expensive machines as he had bought him self a race car (Bugatti) he had put the james on ebay but was local so he let me go round , we talked about the bikes for about four hours (I could have stayed longer) , its not Ariel and he did not know either but was not very interested .

heres the james project

this is the box which fits the frame , any idea going on the numbers

Hi, I think the Burman gearbox is a bit earlier than your frame and gearbox mounting looks a bit modified. Is there any frame number? For some reason Royal Enfield comes to my mind. Are you going to use this Burman gearbox in that frame, if not, is is spare for you, sale? Cheers.

what year is the box ? it fits the frame perfect but i dont think it will handle the power , i have with it a ridgid triumph box which i may alter and use so this box maybe for sale , which part do you think is a modification

[Kuutiopää]

Your Burman gearbox is mediumweight for 250/350cc bikes from early -30s. Hard to say from your first photo, the gearbox base in the frame looks like modified.

frame is original

Ariels used Burman boxes. And that frame looks not unlike Ariels.....

That squarish lump in the frame in the gearbox vicinity looks odd if its original.
And a 2 stud gearbox wouldn't seem to fit it ?

A good view of the oil tank or front brake will probably yell out exactly what this is.

[mark2]

its not Ariel , the gearbox fits it , frame is original will take pics of wheels and oil take , petrol tank is away being stripped , forks look like webs but wider

[mark2]

more pics , its interesting but I think im in over my head , two strokes are more my thing

[R]

Matchless 250 ?
Could be an earlier year though, and/or that gearbox is earlier, as suggested.

View of panel on tank would define it down closer...
