It's not a double gun, but I just acquired an Ithaca Model 37 16 ga. This shotgun has great wood with borderless hand checkering, the original sunburst Ithaca pad, a 7/16th vent rib, 28" IC barrel and engraving. All beautiful workmanship IMO. Nicest 37 I've seen. Serial # is T above 292XX. Any help on the grade, year and value???
