Can't find any source to help me i.d. my Evans 200 bike. I know Evans went out of business about 1962, and I've ruled out 1958 and older, so I figure it must be built between 1959-1962. The serial number from what I can make out is F317486 B26. Any help would be greatly appreciated. People are asking me what year it is, and I'd like to know for myself as well!
