Thanks, Viscount and East Hill !
Yes, I know about The Swift Club and the "some 200" bikes in the register , I found it before I found This forum here. But I saw that it`s not so easy to get contact with them.
So, some pictures

only something is missing, not complete.
These pictures Were in Estonian forum for identification, I can do some more but ....
Swift`s production were selling in Estonia 1925-37 (??? if the company finished in 1931).
My bike`s nr. is E7921, little one? Maybe E means Estonia , Export or smth? 7921 swift`s bikes are too many for Estonia.
