Hi Dan, as I mentioned earlier..first we have to remove the exsisting bottom to see what there is to work with??.. But, un-numbered fxo aluminum bottoms are out there.. and, East German bottoms (hard to get!!) of the earlier pattern are available also from Lugerdoc... We can make just about anything happen..but is it worth it???.. either as a collectible, or just a desire to have a correct style mag??...
..I will help as much as possible... and keep it affordable... best to you Dan, til...lat'r...GT
