Re: What do you guys think of this stamping?
 

Stamp is good.

I am guessing someone did some work on those rods. I don't believe they were heated. The original pink rods were babbit dipped on the little end, and that is what the silver coating looks like to me. I have never seen the babbit dip look that obvious on untouched factory pink floaters. If they are original pink rods, they were probably blasted or shot peened before being babbit dipped. Traditional babbiting is almost a lost art.

Wow, out of all the pink rods I have had I never knew that. Kind of a little cushion to keep the wrist pin from galling the small end of the rod. Nice, you learn something new every day.

That block has been around for a while.
It was in Oz back in 2006.
