Oiler Cap Painted Over To Seal The Tube?

[painter777]

Has anyone ever seen a Oiler that had the cap painted over so it sealed the threads to the Tube?

I have a scanned copy from a loose page from a Air Force Personal Equipment Officers Manual.
Marked AFM-64 OCT 1954 at the top of the page.
This is packed in a Emergency / Survival Kit if a Gun is included in the kit per the manual page. The page gives instructions on how to cut the painted seal away to open the Oiler.
The photo scan I have came from the paperwork I have on the Bomber pilot LT Col Swanberg, Whose Carbine I did a write up about here on Milsurps. I'll put a link below to his story.
From my nearly 3 full binders about 'Swanie' My Photo Scan is barely legible, but I was able to find another exactly like it on another site.

I have no idea what color might have been used, or how it was applied. Considering how the page recommends removing the Painted Cap from the Tube, I suspect the Cap was Dunked deep enough to cover the Threads and upper part of the Tube.

So, Has anyone seen a Oiler that looked like it might have been painted on and around the Threads at one time? Maybe one with remnants of Paint on the Cap and in the Knurled area?

how it was applied

I would have thought that the oiler was simply "dunked" upside down in the paint, enough to cover the cap, then withdrawn and allowed to dry. I wouldn't have thought that someone applied the paint with a brush.

That would be the way I would see it done too.
