did you look on the left rear dropout also?the number you gave doesn't match any documented numbers i found.a chance it could be an early 52,but pictures would really help.are the dropouts open at the rear or facing forward?

no stamp on dropouts

there is no stamping on the dropouts and they are rear facing i will try to upload pics this afternoon
