Thanks Phil, I was most curious about the date of manufacture. If it was some rare type the manufacturer or seller might be more important.
The post-manufacture fillet welds, presumably a repair job, are an interesting aspect. My dad owned a welding business, and his policy was never to charge kids for bike repairs. Over a number of decades there is no telling how many bicycles he fixed for free.
I have all the parts for this one, and for $25, it is worth cleaning up, painting, and restoring (At least I think so...).
Thanks again,
Joel
