1965 Corvette Non Power Brake Master Cylinder Casting Mark location

[Gary G.]

I am looking for a picture or information on an original 1965 Corvette Non Power Brake Master Cylinder to confirm the location of the casting number. Looking at the bottom of the master cylinder on my car, with the mounting flange facing away from you, the casting number 2225032 is located on the right side next to the cylinder barrel just in front of the mounting flange. I have seen pictures on the internet of master cylinders with the same casting number, but on the bottom of the barrel and the numbers are larger than on my original master cylinder. I have owned this car for a number of years and believe that this is the original master cylinder. Any info would be greatly appreciated.

Pictured below is the M/Cyl. that I removed from my 1966 Corvette (Feb. 1966) about 1980. It has been in storage ever since. I believe it to be original but I can not verify. I bought the car in 1979. I buffed off the rust with my wire wheel to see the casting numbers "2225032", some kind of symbol, and "R2". When I get a chance I will buff the rest of it to see if I can find a date code.

I did a little more buffing on my original 66 M/Cyl. to remove surface rust from my wire wheel. Besides the "2225032", strange symbol (possibly a cursive letter "B" for Bendix), and "R2" casting numbers I also found a casting date "325", the 325th day of the year or Nov. 21st. I assume the year is 1965 since my car was made in Feb. 1966. One of the spring clips has to be removed to see the date code.
