Old Mitsubishi DY-337 Year?

[Emmet2]

Hello — I’m trying to determine the manufacture year of a Mitsubishi (Chandler) industrial sewing machine, model DY-337. The serial number is 088045 (stamped on the metal nameplate). I can send photos of the nameplate and the whole machine. Can anyone tell me how to decode the serial, or what years this serial range corresponds to? Any help identifying approximate decade of manufacture would be much appreciated. Thank you!

I moved your post to leather sewing machines.  I think you'll get more response here.
