Did I get a good deal for this Model 1887?

a href="http://www.liveauctioneers.com/item/6956315" rel="nofollow"http://www.liveauctioneers.com/item/6956…/a I won it for $650 (which is 50 less than the minimum estimated value) as you can see its a relatively early production model (SN#2037) so it's probably from the first model year (1887).
