Its not the rough condition that the mid war Mosin is collected for , its the arsenal and year, because most of those years rifles were destroyed in the great retreats. The rough exterior finish was part of the history with these rifles.
rearseanled rifles are not as collectable as unreferrbed, and condition, not machining marks is where the value lays.
There are "Rough " Hex recivers, as most 1919 and 1920 Soviet production was at an all time low with mid Revolution problems with trained personel and battles around the arsenals for their control. The Soviets went to lengths to remove most of theses dated rifles as poor machining was noted and abhorred then. In 1942 with Germans IN the country, it didnt matter what they looked like as long as they were in spec.
'Hex' were made untill the early 30's when round broaches were used to cut the outside of the reciver and save time and achive the same strength.
Even at the end of WW1, weapons in all armys were made to craftsman's expactation, it wasnt untill WWII came along that quick sheetmetal production and guns like the STEN and PPSh-41 and Stg-44's became the rule........with untouched industrial capacity, the U.S. could still make huge number of Garands, all machined and "purdy"
