I believe Broadways were Lightning Models, just had wide ribs. Catalogs didn't refer to them as Lightning Broadways, but I think Broadways have receivers marked "Lightning". I don't have one to examine, unfortunately. All Trap Models had big forends, even in the long tang round knob postwar era. They may have been a little smaller than the later models, but even the early postwar Traps had a larger forend than field and skeet models. They were actually pretty graceful looking in contrast to late skeet and trap model forends.
