Hi Boomer,
He looks very much like a GR. Try not to look at pics found on the net...unless they are the local bred GR's..not frm any special bloodlines.
Most of the GR's on the net are top quality show dogs. So yes,they have broader muzzles..broader chests...longer fur...etc.
But compare urs to other local bred GR's...urs looks pretty typical to me.if he is mixed,then i say his GR genes are pretty dominant...but i think to pay 1100 for a pup w/o a cert is...wow..alot.

P.S. He's got very pretty eyes

Here's a link bout different "types" of GSDs. Enjoy
