I had an SKB 600 Trap in the early 1970's, back when Ithaca imported them.
So people used to say, back then, they were "better than the Browning's". I have my doubts about that now. IMHO, they occupy a space slightly below the present day Citori, but are still above many of the mid price o/u's.
Personally, though I have a Citori Trap, I do prefer the way the SKB trap guns fit me and also prefer their weight distribution.
The problem, for me, is, they are not currently sold or serviced here, in Canada. If they were, I would consider one for my own use.
A new guy at the club has newer trap model (I forget the exact model No.

), with a monte carlo stock and 32" barrels that suit me very well. He bought it from a guy that brought it in from the U.S., privately.
I had somewhere around 20,000 shells through my 1970's SKB when I sold it. It did break the spring for the lower barrel around 15,000 shells; this was the only issue it had.
