Old .22 mag - new boot grips?

[Armybrat]

My little .22 Magnum is kind of old - can't remember when I bought it. Maybe 20 years ago? It's serial # D500XX.

Anybody have an idea as to it's date of birth?

Was wondering if the new boot grips offered by NA would fit it. That bird's head grip is too hard to grasp even for my small hands:

Very nice looking for 20 years old!!! Looks like it needs to get out more often and maybe a nice set of new grips, like some Spressors!!!

 New made grips should work just fine only a little tweaking with shims or filler to tighten them still . Good luck with them .
