That's a nice find - and it's in guideline condition, too. Period-correct C-Record, first-generation Ergo and Deltas. It might be just a little high, but remember: you might pay more if you pieced that together yourself.
It's definitely authentic - and original.
If it's got everything you want - and you say yourself you came across a small fortune - then what the hey, right?
It's not junk, that's for sure. FWIW, most of us here are cheapskates at heart, so you may hear a chorus of "too expensive", but that doesn't really mean it is
Good luck - you could do a lot worse than pick this beauty up and ride the snot out of it.
