aside from any type of paint as noted above, , IF the front blade is "pinned" one can have another made up (custom) otherwise, I doubt anyone is out there marketing stuff for an item that is long "discontinued"...see this all the time, folks looking for accessories for a firearm that is no longer made by whichever manufactrurer.........back then there were few if any companies making replacement grips & sights, and once the market is 'gone' they start up for the next, latest item (fads & gimmicks we call them)
believe me if there was $$$$ to be made, they'd be doing it............
improvise or customize :wink:
