Mack NR color

[Slava]

It's interesting too by what the way the chap does making plates. A friend of mine uses the place there people makes them of the black lack on alluminium.
I need some of also by my old iron has solid zink tables with chemically relief.

Yea, does the plate indicates a volume of flued required for correcting due to pressures combination?
And does the gun ready to fire?

Any help and all the best
