Hi Ratina. Thank you for the response. Here is the serial number. G61665 then A and possibly C. Does that help at all?It was built between 50-54. Serial number will tell exact date.
The seat, chain guard and grips are wrong. Rims might be too.
Also, given the pictures I posted, and the non-correct pieces you identified (at least those, I'm sure), what would you all do with this? Strip it and redo it, try to get original parts, or just ride it as is? The tires are mismatched and have cracks, so they at least will go. The gray paint on the rims is chipping also.
