Kaywoodie Thorn pipe find

[BryGuySC]

So my wife and I were perusing a local antique mall, and I happened upon a jar of pipes. Most were junk, but I noticed one with an interesting shape and saw that it was a Kaywoodie. So I stuck it in my shirt pocket and ended up paying a really good price for it.

Here is a quick pic, and then I have some of my findings so far.

It has a four digit shape number. I see online that typically puts it pre-1936, but I'll get to that in a minute.
74= Screw-in Drinkless Kaywoodie, Thorn finish, black vulcanite stem (1930's)
12= full bent Oom Paul (1932)

The Thorn line was from 1928 to the late 50s.

Although the 74 indicates screw-in drinkless, mine has no sign of ever have threads in the tenon, or a place for the drinkless stinger in the tenon. I read that could make it a WWII Era Kaywoodie. Kaywoodie discontinued the Stingers to save aluminum for the War effort.
Here is a pic showing paperwork from that era.

I could also make out some some fainter stampings.
I see what looks like "MARYVILLE" or "MARYSVILLE" and "15-44" or "5-44."
Or maybe is is "MARY SAVILLE" and something else over the Kaywoodie name. I'll have to look at it with a magnifying glass, when I get home.
Edit: Went back and it definitely says , "MARYVILLE" but also says "CAL" "LAL" or "UAL" above the Kaywoodie stamp.
But the "44" would line up with the WWII timeframe.

And lastly, it looks like someone carved a tiny "JVT" on it. I assume those are just the initials of a previous owner.

So, whatcha think?
Anyone have any more info about these?

Nice grain on that one!

The light secondary stamping is intriguing me.
Had anyone seen this before, or heard of them being stamped with the date and location?
