Hello all,

I am in the process of collecting all the nuts and bolts for my 1952 R51/3 because one of the previous owners decided to "upgrade" it to stainless. I am used to reading the 1955-1969 parts manual but have a question on some of the verbiage in the 1952 parts manual to ensure I get the right parts and pieces.

1) M8 x 1 DIN 934 atr. versus M8 x 1 DIN 936 (without the atr.) Does the "atr." mean it was cad plated?
2) M8 x 1 x 68 DIN 960 phosph. I am quite sure mean Phosphorus black.
3) If the nut or bolt is listed without the "atr." or "phosph." what plating is on the part?

I know all the hardware pre 1964-ish was 14mm heads, not 13mm.

And do any of you know whom may have nuts and bolts that they might be willing to part with to help with my "correct" restoration?

Thanks!!!!

James

Also saw "cad."

I just saw there is also a "cad." in the R51/3 1952 parts book. So, I surmise thats "Cadmium Plated" so i am really not sure what "atr." is then.

Thanks for any help!!

James
