the simpler logo engraved horns were either nickel plated or bare brass originally. They sold for a few bucks cheaper, maybe 50 dollars cheaper than the silver plated horns with more floral engraving.

If yours is lacquered brass, it was lacquered in later years after manufacturing.

They did a lot of this, since lacquer became the norm around 1935 on.

Value. It comes down to condition and how well it is refurbished.

Consider 750 to 1250 set up  playing nicely with any dent ding work done.
