Thanks for the input.
As far as "Heritage series" goes... as I was researching the specs of my drum "Heritage Series" kept coming up.
And then I found the video below..
He mentions that there are only a few made... which kinda goes along with what you said about them dumping parts into a limted run.
And it also goes along with my serial number being 000042.
Everything I have researched on the Heritage Series has all my same specs. Finish, hoops, lugs, double throwoff adjustment, 42 strand snare.
This is my first Mapex snare so I am not familiar with them to know if any of those specs are pretty standard throughout the series or if these are a bit special. mainly the double throwoff adjustment and 42 strand wires.
