Hi MGCollector, are you in the USAicon?I ask because it sounds like your guns are possibly rewelds, or you have got the serial numbers off the wrong parts. H7398 is a Enfield Mk1 (Modified pattern) from 1941, 4T8833 is a Canadianicon Inglis late Mk1m from 1942. Can you post some photos? The serial number will be found on the body, above where the locking pin fits.
