There is a couple of boxlock and sidelock Gorosabel's listed in the 1988 gun digest. The boxlocks listed as model number's 501,502, and 503. The 501 being the basic model starting at $744.00 with the 503, listed at $1122.00.
I have an earlier Gorosabel 10 ga boxlock I picked up in the early 70's for around $150.00. Nothing fancy, about what Chief and Replacement suggest. Although I haven't used it for a while, I did put a lot of heavy 3.5" loads through it chasing geese without any failures or hic-ups.
