Finish on CZ75 pre-B

[actvlsnr]

Hello, I picked up a pre-B and I can't identify the finish. I will post a pic and give as much identifying info as I have.

It is a 1989.
Serial# CXXXX

Color looks like a matte grayish brown.
It is not glossy blue.

For contrast, this last pic shows it beside a  pre-b  polycoat and a pre-b dual tone

That finish is called Phosphate, it is sort of like Parkerizing. That is a great looking example you have there, I would be proud of that one.

Thanks for the info.  Any info on the Series A, B, C in the serial numbers?

Is that "phosphate" finish original? I did not know the early pre Bs came in that type of finish?

I have taken it down and it appears to be original.  Not an expert on this though.

I have found online where in the 80s some were Factory finished parkerised but not found any info about any that were factory  finished with phosphate.   

Anyone have any tell signs that this was refinished?

Only way I've been able to tell if a pistol has been refinished is by looking closely at the engravings/markings and seeing if they are uneven from polishing or from the application of the finish. Of course, if the refinish is done by a very good gunsmith, then it will be difficult to discern.

I have a '92 that came original with this finish.

Parkerizing, bonderizing, phosphating, or phosphatizing is a method of protecting a steel surface from corrosion and increasing its resistance to wear through the application of a chemical phosphate conversion coating. Parkerizing is usually considered to be an improved zinc or manganese phosphating process, and not to be an improved iron phosphating process, although some use the term parkerizing as a generic term for applying phosphating (or phosphatizing) coatings that does include the iron phosphating process.

Parkerizing is commonly used on firearms as a more effective alternative to bluing, which is an earlier-developed chemical conversion coating. It is also used extensively on automobiles to protect unfinished metal parts from corrosion.

The Parkerizing process cannot be used on non-ferrous metals such as aluminium, brass, or copper. It similarly cannot be applied to steels containing a large amount of nickel, or on stainless steel. Passivation can be used for protecting other metals.
Phosphating was an original finish for the year model of pistol you have.

Thanks SP01SHADOW, great info on the process and also on confirming the finish matches the year/serial for my pistol.

My 1991 Pre-B CZ-75 seems to have a black polycoat finish similar to my 1996 Turkish overrun 75B.  It is an A.A.L. import (Philadelphia).  I've never seen the phosphate finish like that one.  I know mine is the original finish as I bought it new in box.

Thanks Pilot1.  Looks like CZ did various finishes in the pre-B era.

One thing I did not mention before is that this 1986 pre-B has no import markings and came with no box.

My CZ 85 Pre B appeared to have standard Parkerizing as the finish treatment.  I'm no expert, that's just the way if looked.

Is the Phosphate finish on these older 75's the same thickness/quality as I would find if one where to strip the polycoat of a newer one?
