jayroorbach Well, the fact I got it from the daughter of the original owner, and it was well known in their family that he bought it new in 1953 (because he had just been discharged from the army and used his pension to buy the bike, to then court the woman that would become his wife) helped. But from the perspective of evidence on the bike, the FB hubs (that are pantographed PAFF) had 52 on the cones, indicating the hubs were 1952 vintage. That put the bike between 1952 and 53.
BTW: you already have the attention of
juvela who has an encyclopedic knowledge of many details that can help identify a bike. Looking closely at your pictures the bike appears to me to be from the 60s or 70s, but as he already said many components (that could offer date codes) have already been replaced.
