To Role-Monroe-Co - the little thing on the head tube, as Viscount said, seems to be somekind steering lock, but something looks missing there. Haven`t seen before, it helps to make this bike interesting for me
Any other interesting machines? As I wrote, we have more german and swedish bikes from 1930-s, I mean before WW II (1940), from 1920 and older we have more less machines. After WW II we got german reparation bikes (Diamant mainly), then latvian (Riga) and after from Ukrain (Lvov/Lviv) and Belarussia (Minsk) and some russians too.

Most of my old bikes Ihave saved from a local firm deals with secondary metal. Some time ago people throw away old bikes and now they are gone mostly.
From UK Ihave only 2 man`s Royal Enfield frames and some other details, from 1930-s. I have more complete Dürkopp 1935, Husqvarna 1936, Opel 1928? ....
In Estonia we have man who has more 100 hundred old bikes, some of them in good condition (for example The King Alfred, sporties 1922) and some restored and some not so big enthusiasts, I don`t belong there, I haven`t no one restored and in good order bike.
Maybe there are some Swifts in Estonia more, I don`t know.
I`ll try to put one bike for identification from estonian Auto-moto forum, probably from UK, a new thread.
