When I see Res-O-Pads such as these, they say, "Original pads" to me. As in, these were the only pads put in this horn. But the bell has that relacquered look to it. Not so much in the engraving, but particularly in what looks like hammer marks near the bell-to-bow ferrule.
So, if it is a relacquer, at what point in this horns life, starting in 1941, did someone decide, or get persuaded, to have it relacquered at the factory? Ten years, in 1951? Eighteen, in 1959 right before they busted the union? I would love to go back in time and hear the sales person at the music store, or the repair tech in their shop, discuss the advantages of having this done.
