Ok, how about this? Code a new option that makes any 'new' 45 mag weapon different, in a date-specific way. Each type, old & new, will have some kind of ID in the game-code that identifies them as old, or new. Also, to avoid confusion/deceptions, anyone looking at one will see in the weapon's name/description that it is old, or new. 45 weapons made
after this set date will cost less & if melted, yield less, & those older 45 weapons made
before this set date will remain unaltered, & if melted, will still render their full worth. Possible?....
