This is a great topic, IMO the model 21 is an ugly, over engineered unbalanced base ball bat, in the UK you can buy them at auction for about GBP1000 (decent condition) but in the USA some guys are paying 5 or 6K USD (or more) for them !! There must be an arbitrage here. I suggest any of you chaps in the US who want one of those things looks in at the UK firearms auctions

best, Mike
