Keg identification help

So, I've got a couple of these old 10 gallon kegs. They have no markings on them, other than a serial number. The in/out posts on them are ball lock, but the thread sizes are different than my 5 gallon corny kegs.

The bev out dip tubes are also a little bit bigger than the 5 gallon kegs. They also have these weird plastic inserts that go between the poppet and the dip tube. There is no gas in dip tube.

One of these suffered a bit of an accident and one of the posts is pretty bunged up.

Can anyone point me in the right direction of where I can buy some replacement in/out post assemblies?

Thanks in advance for your help!

 

To keg outlet . Com and ask them.

 

I think I've got it.

From that site, and measuring the threads for the posts, it looks like it's either one of these

John Wood 85, Firestone Challenger
Gas 11/16" - 18
Liquid 3/4" - 18

Luckily enough, it looks like Williams Brewing has the parts I need!

Be nice to get these back in service...
