Piston ID

[Randy/In]

I removed these pistons from a 1935 engine that I plan on rebuilding. I have never seen these type with the piston pin retained by a circlip in the connecting rod bushing. I am wandering if this was common? Randy

I have a set here somewhere as well. Not sure what they came out of.

They were original style Ford pistons. Original Model A had that same set up. I don't know when Ford did away with this, early 30's I believe. walt
