These valves have been rebuilt so many times I was having issues with correctness.
Here is what I think the various finishes were in 1967. I'll update as I find pics and get better data on fasteners.
* Steel tube with tapered stud inside: Bare steel, tumbled. Bluing around weld.
* Orange plastic seal between tube and body (somewhat visible)
* Stud seal Clamp: Bare steel. Closed style, top at stud.
* Stud Seal Clamp Screws: Straight slot; 0.5 long; round metal type screw; blunt nose; silver
* Clamp at tube threads (to drag link): Darkened bare steel
* Bolt to above: 5/15x24 Grade 5; RBW 3 radians - 304759-S2
* Nut to above: 5/16x24 Grade 5; cone lock - 34443-S7
* Tapered stud: Black oxide
* Bolts from tube to main body: P&O; M 3 radials.
* Main body: As cast, slightly darkened
* Cap: Raw cast aluminum with machined surface at end for date stamp
* Cap Screws: Straight slot, captive lock washer, black oxide
- Pic 1) Restored tube
- Pic 2) I've decided that I've seen enough "M" with 3 radians to accept that bolt.
- Pic 3) A view of the stud seal clamp bottom. This clamp is reproduced, however, this is an original. The blunt screw is also picture with its length.
The clamp is bare steel. Note too the half round cutaway around the zerk area and how tightly it fits around this area.
