[R-390] Tube Shield Questions_OT

[DQ]

I am only asking this question here because there are darn few
questions that remain unanswered, whenever placed before this
forum. Theoretically I suppose that some MIGHT fit a few R-390
tubes, so maybe it really isn't off-topic. That having been
said:

Today I dug out my hodge-podge collection of tube shields and
I've been going through and organizing them. At the bottom of a
box, below the IERC's, and all of the various spring loaded
ELCO's, EBY's, CINCH's, and what appears to be 160's, there were
what appeared to be some cheesy looking cheap tin slip-sleeves.

For lack of a better word I will describe them as having small
horizontal 'stiffener' beads. Some of them sort of looked like
tube sheilds, and the more conical ones did and didn't at the
same time.

After getting out the magnifying glass I pulled up a name and
patent number: Staver Mini-Shield - Pat. No. 2499612. I looked
up the patent and sure enough, they were in fact tube shields,
and they were patented May 7, 1950. My question to this esteemed
group is this:

Were/are these "correct" OEM's for some long gone tube radios,
or were they just cheesy aftermarket wannabe stuff? I don't know
whether or not to give 'em the heave ho, or if someone might
want them for a particular flavor of tuber to make it original.

Also, I came across four other medium sized, bottle shaped, tin
sheilds that are two-piece (8 halves total) and are held
together via a round circular spring-clip. The same question of
origin would apply to these as well.

Thanks guys, ~ Quig ~
