I have some small kegs (2.5 - 3 gallon) with no markings to reveal if they are corny, firestone or spartan. I also have an assortment of posts, some pin but most ball lock. I have no idea what goes with what. I can only try them out by charging the keg and leak check. Most of the posts look like spartan but there are some pin locks that don't look like anything. And the poppers all look like they should belong to corny posts but, like I said, none of the posts look like corny. So.... How much interchangeability is there with these things? Or should I just RDWHAHB? of course, I am doing that but also trying to figure out this mess of kegs I have.
Ps. I bought these as partmof a much larger all grain system and the kegs and Co2 stuff were incidental. But now I am aiming toward 10 gallon batches and legging needs to be part of that. TIA
