ID/notes? fill stations & random air bits, tippman-ish valve. PCP air rifle maybe

[mercpb]

I have a random lot of bits here, looks like a couple PCP air fill stations based on this link:
https://www.actionvillage.com/Ninja-...-ninja-pcp.htm

... and then some big brass tippmann style pin valve.
Stuff is foreign to me - it all looks to be air rifle stuff best I can tell/google.

Anyone familiar and/or have tips or comments? I just want to get it moved on to someone that'll use it

I'm thinking that valve is PCP as well, everything there might be PCP. That valve looks too large and doesn't have the parts to run air back to the barrel
