What are they?

Just saw these in the Facebook market. No description.

I don’t know what they are. I don’t even know how to detonate them.

Looks like someone ripped the limbs off a bunch of C3-P0 droids! 

But I'm sure @jsharr will GIS and let us know ASAP!

You can get an estimate of their size by the person standing in the background.

They almost look like catalytic converters but where would they get that many that are all alike?

Someone cut the converter out of one of our work vehicles this summer. Apparently there is a good market for them.

Most scrap yards will buy them. The no questions asked scrapyards pay around $30.00 each.

Chicken dinner.     Ford 350 catalytic converters IMO  BC34...........CA is a valid part number.  where the ........ is the model number.

That looks like it. It only leaves John's question about how a collection of that many of one type comes to be.

Catalytic converters contain several grams of platinum and other metals that are worth acquiring. From a CC recycling website:

Whoa! That has to be sale prices and not purchase prices. Otherwise, no automobile would be safe from scavengers. It would be like the Walking Dead out there.

Almost 3000 stolen in the first half of 2019 in London alone.   https://www.bbc.com/news/business-49767195#:~:text=For the first six months,they exit the exhaust pipe.

I'm willing to guess that the numbers are equally large in parts of the US.

When I had an F150, I was told to install a cover over the catalytic converter to keep it from being stolen. Trucks and lifted trucks were targets as they could scoot under with a sawzall and cut one off in under 5 minutes. Didn’t do it and never had mine stolen.

I was going to guess Dead Sea Scrolls from the first pic.

I was going to go with combustion chambers from can annular engines. 

I suppose it depends on your point of reference.
