Your barrel is for the Model 1911 in the serial number range from approximately 110,000 to 420,000. The common leg HP was used from just over serial number 400,000 to the end of Model 1911 production in 1924. The slide appears to be the late style marking, so a receiver would have to be in the proper serial number range for a match. Normally receivers by themselves are virtually impossible to find, so you would probably have to buy a parts pistol with the correct serial number receiver if you wanted them to match.
