Somebody correct me if I'm wrong but, didn't USD make a J valve with an SPG port on the LEFT side? I know other mfg made them with the port on the right, but I thought USD made one with the port on the LEFT.

If so, could someone post a pic? I would like to locate one.

THANKS IN ADVANCE
 
I have at least one of each type of USD J valves produced since 1955 and I have not yet run across one with an SPG port. Some, not all USD K valves have an SPG port on the left side
 
Captain, can you post up a picture of one of these valves? I have never seen a valve with a SPG port. THANKS
 
Here are two. The one on the left is from DACOR and the SPG port is angled down under the knob. These are pretty common. The USD on the right has the SPG port on the side and in line with the valve knob (the blow out plug is on the back). I have never seen a USD valve like this before I got it from EBay.
