[STEINBVG]

My special thanks goes to GT- he did a great job fitting a nice Mauser toggle for my upper slide/ barrel he recognized as a ww2 Mauser armorers kit. He went above and beyond, replacing with his own my mismatched and misfit modern ejector and main pin.
Today I have tried this upper on my 1977 Interarms lower.
The side plate from 1977 doesn,t fit as you can see on the pictures- 1977 doesn,t have a ridge above the sear.

And p08 Sarco remake I also had to modify for perfect fit. I will clean and blue the grounded surfaces later.
The result is - an excellent shooter.

Now I will leave the 1977 upper alone with “low mileage” , having shot through it perhaps only 3-4 mags.

Again, GT, YOU ARE THE MAN!
