Im looking at a slingerland set from the 80's and the badge is black and gold.. simply reads USA on the bottom. I dont see a badge like this on the vintagesnardrums.com site but i did see an image of one here on this forum, another member pointed it out to me and told me this is a musicyo import kit.

Is this true? why would they write usa on a taiwanese drum?

also if it is an american made set, will there be any writing inside the shells to look for?

according to a drum timeline if came across, gretsch owned slingerland as of 1980. did they build the drums with gretsch parts at that point or was that not untill the ridgeland days?
