Eimac SK510 air system socket for 4-1000A, 3-1000Z, other stuff

I've got a real Eimac, made-in-usa, air system socket for a 4-1000A tube here. It's an SK-510, and is used. I picked it up thinking it would fit a 4-250/4-400 but I was way wrong.

Also have:
(3) Millen 100060 1/4" shaft locks
(4) 8950 RF final amp tubes (specialty sweep tubes, basically-very expensive on Ebay!)
(1) T160L/572B Cetron brand, new in box
(1) Spectrol Multidial Turns-counting dial, model 30-1-11 (counts 0-9 rotations)

I'd like to trade it for something more usable for me. My big transmitter project is a 4-125A modulated by a pair of 4-65A's, and I already have the plate iron, modulator tube sockets, and final amp socket. I pretty much have everything I need for the 6 meter RF/mod deck to fit in the rack, so I am looking for:

Exciter parts:
Millen 69046 slug-tuned coil forms (need 4)
National XR2 coil forms (need 6)

Power supply parts:
Big HV choke (my plate iron does 2300VAC and is not center-tapped)
Big bleeder resistors (my filter caps are 115uF at 2300VDC)
Vacuum relays/high voltage relays for switching plate/screen supplies on/off

RF Deck parts:
Plate tank components (DC blocking capacitor, plate tuning capacitor for 80-10m, plate feed choke)
Filament choke or choke parts for 4-125A (5V, 6.5A)

Misc:
grab-bag lots of higher wattage resistors (1W, 2W), handful of high voltage ceramic/mica/polyfilm capacitors, IF cans from tube radios, etc.

If you want to trade or make an offer, just let me know.
