My mistake then. I was under the impression that "blackout" hubs were indeed Parkerized? I hope I'm not cornfusing anyone.I don't think it's a blackout hub Mike. If the last number is 10 then it's a heavy duty hub and would be correct for G519 military bikes and also service bikes and cycletrucks. These hubs had a Parkerized finish which has a dull sheen.
At some point during the war Morrow started doing the blackout finishes on next hubs to come down the supply chain. Shaun's example he has for sale doesn't note the date coding or spoke gauge. I have had three or four Morrow blackout hubs and they were all dated 45 and none of them had the 10 gauge spokes they were 13 gauge.
I hate you, I'm going to be looking at Morrow arm script now ! (-:
or perhaps a date code? s=1949?Perhaps S is for subcontracted pieces (based on total guesswork?)
As good a theory as mine, that's for certain. Some 1949 dated hubs with these arms would help corroborate this.= Rustjunkie
or perhaps a date code? s=1949?
just looked at some nos arms on eBay, non-stylized script, no extra letter
Because it's a Wartime"Blackout" hub & the surface has either worn away or been stripped.
Morrow Coaster Brake Hub:
Letter and number note the year and quarter of production.
Example: I 3 = produced 1939 July-September
Note: many hubs are marked 36-13, this is not the date code, it notes the # spoke holes and size.
