Hi I resently got a realy old jocky box withmade buy shlitz with a tap a cold plate, a realy old metal cooler and all the hook ups including a hoff-steavens coupler. I was going to convert it to use with my corny kegs. So I have no use for the Hoff-stevens tap or atachments . Are they worth anything or junk . Oh and I also have an antique co2 regulator. Any help would be appreciated. Thanks. Dan
