Anschutz magazine question

I have a 1416 Anschutz. I purchased a non factory magazine for it and can not remember who made them. I have tried to google it with no luck.
The Wisner 5 shot Savage magazine is a good non factory replacement - They're all I use in my 64 & 54 Anschutz sporters.
 
No, I haven't personally tried the 10 rounders - I know fellows who have with varying rates of success - Apparently they can be modified to work but I've been around Anschutz rifles a long time and even the factory 10 rounders are known to have issues. I currently only have one which feeds reliably and it is fitted with a CZ metal follower adjusted to feed at the correct angle. I also had to modify a spring to suit!
