I scored this kit - a TJ Percussion. It looked like it has brass lug inserts, the shells actually have reinforcement rings and the lugs looked like big thick Tama-esque tank parts!
Well, while it was still a good deal, the lugs left much to be desired. At least they function, so long as it is not torqued on I suppose.
I just thought I would report this discovery so we know.
TJ Percussion - not sure if this is MIJ, MIT, MIC ?? Likely MIA though.
