Art & Inspiration Piston origin? Thoughts!

I was in search of some tools today and found this ashtray that I had long forgotten about. My grandfather, who I think machined it into its current form, always had it sitting on his basement workbench. Any thoughts on what it may be out of? Most likely it would have been something pre-50s. It measures 3 - 13/16" in diameter.

 

Looks like he made it into an ashtray. (I can't remember the last time I saw an ashtray. They were once common)

 

I’m going with Joe Camels engine after he tore it down.

 

My guess would be some kind of hydralic cylinder. I don't understand the lack of a retaining mechanism for what would be the piston pin.

 

My guess is that it was never a piston, just an ashtray, if you look at vintage ashtrays a lot of them have grooves around the base.

 

Probably 2 stroke .

I’ve seen some pistons with that weird wrist pin set up out of old snowmobiles.

 

It's not quite a 327 piston, but then again it's not much different.

 

Yep, made several into ashtrays back in high school.

 

Standard piston ashtray, at Squeak Bell's place.

 

Definitely was a press fit piston with half of the wrist pin boss machined off. Possibly had a skirt at one time that was machined off also.

 

Don't know what it is, other than cool!!

 

In HS metal shop, we melted down old pistons and poured ashtrays (shaped like the US) for our moms to use as mother's day gifts.

 

Some of the early Detroit Diesels I worked on had multiple piece pistons.

 

I have very similar looking ashtray somewhere...
I was told its from my grandfathers car.
He had 27 cleveland and 28 plymouth.

Also 52 mercury and 65 rambler but that piston dont look so new.
