ROLLFAST I.D.

[Cosmicflyer]

Any help would be appreciated identifying this rollfast... I think I've narrowed it down to 41 or 46... Just got to clean up and ridable condition. Rides like a dream.
The only serial number is on the seat tube..

Morrow rear hub date code is not legible

I believe that curved downtube came out in 41. Definitely not a post war bike. Sure there's no serial number stamped into the bottom bracket?

Thanks, Definitely No numbers on the bottom bracket and the number on seat tube is 66634

looks like a top-load delta?
the 1941s and 1942s I've seen are BB stamped, 1942 has date code also?

Yes top load delta

Serial numbers on the seat tube mast, (often a letter followed by 6 digits), might be a post-war indicator.
So post-war there may have been an immediate short-term transition period, that used the good old fashioned rear-facing drop-outs.
The seat post clamp area also looks like the then-former pre-war style.
The seat post itself looks peculiar, not 5/8" shimmed; wonder if it might be a "shorty".
