John, back in 1970 bought my wife a BL-4 28 ga for skeet shooting. 26" barrels, imp.cyl./mod. She shot it some, I shot it a lot more and really liked it. Used it for stocked pheasants and did well with it. Still own it, and it is still in like new condition.
I do believe it was imported by Garcia out of Teaneck, N.J. Nicely made gun for under $300.00 back then. A little more engraving and ejectors compared to the BL-3.
