Reworked old motorcycle frame .

Is this some british motorcycle frame ? As you can see it was heavily reworked

Nothing British that I'm aware of. Probably post war with swinging arm. A long frame number, which might indicate a good number made (?). Eastern European?

No idea what it was originally but looks like a scooter frame with (quite tidily) added top tubes.

Check if the wheelnuts are metric or imperial - that will give a clue as to origin.
The rear wheel sprocket on the right might be a giveaway - if the wheel is in the correct way.

Looks like quite a lot added to it - for competition perhaps ?

All spokes are with heads on the same side , I dont know why . Wheels look like from german  DKW SB 350 . Back shock absorbers are from german MZ from 70/80's , front shock absorbers is back absorbers from Polish small motorcycle WSK 125. All conversions are very amateurishly made many pipes,  welds and sheet metal
That is how it looks now , I think the back of the frame was without shock absorbers , back is made from some other tubes

Looks like one of the scrapyard specials from the wilds of eastern europe or the balkans pre glasnost.Its obviously seen fair use for a period ,probably until someone saw value in the motor and gearbox,and sold them on ebay.

It is from Poland  (I am also)  It was made probably for transport  sidecar use to bring things from fields in some village , I have showed those photos on few motorcycle forums in Germany and Poland but nobody knows  what motorcycle  it is :-( I am interested in old motorcycles since 1999 I have 23 prewar motorcycles but despite this  I can't find the answer
