Thank you guys for your quick responses and interest. To be honest I don't know why we thought it was a model 222 - probably because there is the number under the top lever 222 114511.

I just want to clarify that the rifle has original parts but has undergone external upgrades. My old man is a geek grin on this subject and has a lot of free time. He has been working on guns for over 35 years.
I guess for some it is unacceptable to violate the authenticity but there are different people with different taste cool.

Again thank you for the support guys!
