I sent an email to Herman Burgos who has the web site on Miyata catalogs, the following is what he wrote back, I've sence sent him pictures. If he is correct, maybe the serial number will tell the story.
Dear Dave:
I do not have records for your 1937 Miyata Bicycle , but it will be a good idea to have the picture to see it. At this time Miyata used to have the date on the serial number R 937(year), now the first letter is the year.
Regards,
Hernan P.Burgos
Kevinsubaru, I think the fender ornament is cool too, the entire bike has a very 'antique' flavor. I'm not saying that the ones who think it is newer are wrong, it certainly could be and all the comments about it being a 60's or 70's bike certainly have merrit. I do believe that if it is a 60's or 70's bike, it was one of those bikes that was in production for a long time and carried a lot of the pre-war style with it. I'm just hoping to find out what it really is. Thanks, Dave
