Need help dating a greatcoat

[AHollis13]

I've had this coat for a few years but have never been sure of its age.
It seems to have a name written above the inside pocket "ЗБРОЖЕК", with what looks like "1910" and maybe an "RS" next to that. Could 1910 __ be a unit designation?
I can't read the smaller box (under the large 52-3), but sometimes it looks like a 60Г (1960 год?) above the 40.
As the second picture shows, when I found the coat it had soviet airforce insignia.
Thanks!

Hi, it is fairly modern.

The "52-3" is the size. Which is also repeated in the other box. "Poct" being the word "size" in Russian.

An "r" after a number would be a date.

Cheers, Ade.
