BE Nightmare Help

So I just picked up a nice Nightmare with a bad leak. It drains the 12g down the barrel in 2 seconds. I opened it up, seems like its missing the front seal in the valve? Does anyone have a picture or diagram of the valve exploded? Just so I get an idea for what I need to find.

I just learned parts are rare, anyone have a few to sell?

Thanks
Spec.

Wow. I'm missing a few seals....

Anyone know where to buy complete kits? Or the sizes of the seals, and I can get them locally?

I made/make the plastic seals for Cobra/Nightmare valves, the "V2 - Brass Nut Seal" from the diagram. It was bad in both valves I have, and it helped a couple other Cobra/Nightmare users. The "V5 - Valve Oring Seal" seems to be oring size 009, and the "V8 - Valve Body Oring Seals" maybe stretched 112 or compressed 113, not sure, mines are well used. Hope this helps.

There are no more commercial seal kits..long gone. If you shredded the "magic" o-ring, you may be in for trouble replacing it. See the Brass Eagle section in the Armory for more help.

Reviving this thread a bit.

MorueM said that V5 most likely is o-ring size 009. But was unsure of V8
In the picture there are two "things" in the V8 position. Are those two orings? Do you put both of them in the valve at the same time?

If my working non leaking nightmare SB comp is missing both valve oring seals (if indeed there are two), one could wonder why they are there and what they should do.
If I remember correctly I put V5 in V8's position, then the washer, spring, valve stem, valve stem seal, brass nut. No V8 orings at all. Maybe it was just pure luck it didn't leak?

Anyone care to take a slightly more modern picture of the assembly pictured above. Maybe even in colour with the known facts written on the right places?

The 2 orings at the V8 position go on the outside of the valve assembly. Pretty sure I used 112 ones when I rebuild my Cobra, bigger ones would slice a little too easily going past some holes in the body.

113 would be the factory size but you're right, 112s are much easier to get in without slicing them.
