What points do you lubricate on a D-frame? Does it require removing the sideplate? In the absence of guidance otherwise, I would take the opportunity to drop a bit of oil/BreakFree/etc. into any opening or rotation I could reach. In other words, I'd oil the ejector rod from each end and work it back and forth. I'd put a drop of oil in the crane pivot. I'd drop a little in the breech face slot in which the piece rotates the cylinder gear. I'd put some in the cylinder lock slot. Finally, I'd cock the hammer and oil the hammer pivot and the exposed slot. In addition, maybe someone could tell me the actual names for the parts I've just mentioned... I've just bought this 1976 DS that looks new. I expect it needs some attention.
