Can't help with how many but they weren't around long. I had one but never fired it, planned to give it to my son but he grew tall too fast, so it would have been a might short. A very fine little rifle though! Wish now (as always) I had kept it. I believe they made them in 22 LR and 22 Mag. Mid 80's would be correct time period.

I found that site also. Doubt they are still for sale, My guess is it's an older add. Also after reading it, I'm not sure how "authentic" they are. Says something about a bad crown and cutting and recrowning? Sounds like someone may have put a full size action in a short stock, or made their own stock. Who knows. I grew up shooting one, thought I was in heaven when my dad found a 10 round clip! I used to have blisters from reloading and shooting so much! Let me know if anyone finds out how many were manufactured. Thanks again!
