Hi
@HarveyRanch
That's nice, an early dated Morrow hub. I've not seen one in this early format before.

Here's a 1917/18 one I own, the stamping is side to side, like yours, but the format is a little different, and gives the full patent dates. By the time yours was made, the patents would have expired.:

So, yours is a 36 13, which is a typical number of holes and spoke gauge.
B3 is July to Sept (Quarter 3) of 1932. Codes start at A1 in 1931.
This links nicely with
@Archie Sturmer 's date of 1932 for the frame, and it seems likely that it is the original hub. If this is the case, since the hub needed to be made and then delivered to Snyder, then the earliest the bike could have been completed is July 1932.
Best Regards,
Adrian
