What is this ?????

[Vulgunx]

Went to go pick up a dexta with my friend today and it had this on it me and my friend who has collected dextas for years have never seen this before?

I think its a DAR valve. Very rare. gives double acting hydraulics.

I think* mine has something similar, however its just a small knob without the lever...shuts off the front loader or the hydraulic arms, if u wanted to use one or the other. I could be preaching to the converted here though
