I definitely have some Firestone ball locks...they were some of the first kegs I acquired 20 some odd years ago.

Maybe Firestone made both

I also have some firestone ball-locks. Always wondered if some of them were originally pin-locks that have been converted?

There are lots of 'converted' ball locks on the internet. I've seen pallets of them at homebrew shops, but that's a recent response to the short supply of ball lock kegs. I'm not sure about ones purchased 5 or more years ago.

I think you mean that these are ball locks, but the posts have detail differences.

For ball locks, you need to know that there were several manufactures, Firestone (I know I have some of those), Spartanberg, Cornelius and John Wood (never seen those). There are at least 3 different posts designs for corny kegs, Northern Brewer calls those A,B,C type. Williams Brewing also has a breakdown by manufacturer.

Pin locks are shorter and wider, I do have one that was converted to ball lock.

Joe Sr.:
Jeff is correct.  There are different manufacturers of ball locks.

The posts will be different in the threading as it attaches to the keg, the poppets are different, the pressure relief valves are also different in some cases.

The posts have different overall heights, but the ball lock fittings are all the same.

Nowadays, with the universal poppet, some of the differences are less important.  But, if you take them all apart at once you need to get the right posts and poppets back to the right kegs or they don't fit and seal correctly.  I know from experience.

Converted pin-locks will be a different height and width from ball lock kegs.  I believe shorter and squatter.
