). the frame's bottom bracket shell is agrati nr. 000.8507 and will likely be threaded italian, even though the threads are not used in the thompson system. a traditional three-piece bottom bracket assembly could be mounted straightaway.
the frame's head is bulge-formed and made by agrati; it is item nr. "EXPORT" with angles of 72 & 63 degrees. length/height is likely 140mm. the seat lug looks to be the agrati nr. 086.8569.
my guess is that we are in one of the germanic countries of western europe here. if i had to go out on a limb and guess a specific nation i would say germany. no ideas as to manufacturer.
Thanks a lot ! it`s a lot of info ! do you have a catalogue to get the information ? because a googled agrati and there int's much about it on the internet...

thank you, I was expecting to be something middle leveled, due to the lack of references on it... I bought it as a chrome-molybdenum, is there a way to make sure it is cr-mo or not ?
