Were the sidle lamp brackets for the 1909/10 T's brass or black? Also, were they offset or straight? The ones on the '10 that I bought are brass and offset quite a bit, and I think re-pops plus the lamp doesn't seem to sit on it very well; you really have to monkey with the lamp to get it in the exact right spot for it to tighten up and sit kind of straight
Originals were brass plated steel.
Counter sunk holes, somewhat short offset.
Good picture of one on page 39 of Bruce's Big Book.
