My 126.19300 just has Sears name no J C Higgins. Seems to be a 1400 Crosman to me. Easy to reseal with the right kit from Mac 1 for a 1400 that I used.
Here's my 126.19300. Sears markings. Has scope groves. It has "140" on breach cover but safety in trigger guard so 1400. I buggered the exhaust valve trying to replace the quad o-ring. Got a replacement exhaust valve from Mike Baker. Resealed it a while back. Holds air hits harder than ever now.
The telltale difference between the 140 and the 1400 is the trigger/safety locations. The 140 has the safety as a cross pin in the middle of the stock and the trigger pivots in the stock and comes off with the stock versus the 1400 that incorporates the trigger/safety as a modular component the is attached the the pump tube by two screws and is not attached to the stock in any way..

BDHave you ever seen a 126.300 / 1400 with a knurled thmb nut for the factory?I have seen the 126.300 / 140 with the knurled nut, but never the 1400 from Sears.
You're going to have to do some machining on the 1377 steel breech at the forward 4-40 screw area. the rear breech mounting screw holes line up with the pump tube location but the front 8/32 countersunk breech hold-down screw location is slightly rearward from the 4/40 screw location. It can be accomplished with some machine work and patience.BD
