What Lubricants should be used on HW35

[buellm2]

Now that I've degreased 50 or 60 years of dried out grease from my 1968 HW35,  I'm ready to reassemble it.   I don't have any AG specific greases on hand.    I do have some silicone grease, ARH super moly paste and  TW25B extreme performance synthetic grease.   I've been soaking the leather seal in neats foot oil and it looks like the seal swelled up a little.   I'm thinking of using the TW25B on the piston and inside the compression tube.   Which, if any, should be used on the spring?

As for me, I tend to use as less different lubricants as possible. I'd use your ARH Super moly grease on the piston, cylinder walls and on the spring. Apply only a very thin coat, almost transparent, as if you were ''painting'' the parts. Moly grease is also perfect for trigger parts after a good polishing job, yet again a very thin coat is all is needed. I like to use a small artist paint brush to apply the lube.

FYI, I no longer use molybdene disulphide, I use tungsten disulphide instead. A bit better, but moly is excellent nonetheless. I have made a paste with tungsten dry powder and silicone oil, I now use this mix on my piston leather seals, it seems to slightly improve sealing and slipperiness if that's a word, thus power. I install the piston in the ''dry'' tube with no lubricant on the comp tube walls, wipe the walls dry (to remove the silicone lube from the seal), then apply my tungsten paste (dry tungsten powder + synthetic motor oil) on the walls where the piston skirt slides. So far it has given me excellent results. HTH.
