I was able to give these kegs a pretty good looking over,and it appears that 4 of the 5 I have are also Cornelius-Spartan.I removed the lid and removed the gas and liquid tubes (this one has a straight liquid pick-up tube). It looks like it has never been used as both tubes had a dark sticky residue on them. Obviously VERY old syrup. They also look to have been stored outside as several had old soil stuck on the bottom and the seals on both posts looks to be near disintegration from sun and weather exposure.The 5th keg looks ever so slightly different, and that is mainly a maybe 1/4" height difference. I'll have to give it a good cleaning and get the stickers off it.Maybe I can ID it then.I'm guessing it is a Corny-Sparton too, but that will be determined later.
Several of the posts do look like they have maybe been mishandled. (dented and scratched up etc). I'm assuming these see some rough service during their lifetime.
Any idea what I should be looking for in the event I need to replace some of these posts?
I need to remove a couple of the posts and look for the ID like mashdar and mack_1103 suggested in the posts above.
