I have managed to break Anschutz magazine followers and base plates many times over the years. Here's a few solutions to repair/replace them:
The 5 shot steel Wisner magazines (Savage) from Brownells have always been a "drop in" for me on 64 repeater actions. They sometimes need to be modified slightly (5 minutes with a flat needle file) to fit 54 actions. I have never had one fail and they actually work better than OEM mags IMO.
DIP sell metal replacement plates and Kinney's Shooting Supplies in the US ship internationally and would probably be able to supply.
Nordic Marksman in Canada supply EVERYTHING Anschutz and will ship here.
I have bought factory replacements locally from Potter Firearms in Victoria.
CZ metal followers can be fitted to the Anschutz magazine and it's just a matter of adjusting the follower angle to obtain the correct feed.
