You could very well be correct, Chuck ,
in saying that Joel's mystery lug is an Oscar Egg one, particularly as the rest of my mystery - possibly, but unlikely - Garin frame has other Egg connotations eg rear drop-outs, gear braze-ons under the down-tube and chainstay.I know that some Oscar egg frames have been known to have attractive lugwork, but as a species they seem to be very rare. In over 55 years of being involved in bikes and biking I have never seen one, but have been contacted on at least half a dozen times by owners seeking out transfers. Does anyone on the List have any photos or know whether Egg frames had head-badges instead of transfers.. or more likely vice-versa in the 30/40s era.?
My first contact with Oscar Egg lugs was in 1953 when I started helping a local framebuilder, Hilton Wrigley, to clean up and prepare lugs for assembly and brazing. Many of the lugs we were using were cast ones that required hours of thinning and profiling, so it was very pleasant when the first of the Oscar Egg pressed steel ones arrived in their little boxes. These still needed "tickling up" around the pressed -out profile, but much less work than similar Nervex ones which, as I recall, were made by an "explosion" type of process without seams. I recall that there were about six or seven standard designsof Egg lugs
So the mystery lug could well have been an earlier type of Oscar Egg - its appears to be cast - made before Egg turned to pressing, or having them pressed out.
