Rock Ola barrel ??'s

[painter777]

Remember the $10K IP ?

1st picture shows a Real Rock-Ola gas cylinder
Bottom picture from the IP auction of fake Rock barrel




The same seller Ironman is currently offering a rebuilt IP with a RMC barrel (pictured below)
Question is:
Has anyone ever seen a RMC barrel marked/dated like this one ?
Anyone ever seen a Gas cylinder marked like this on a RMC ?










Anyone know if B&P Motor Sales who made and marked cylinders for Inland BI ever supply gas cylinders to another maker ?
Might the B just be a partial stamp ?
Something about this......... Because it's mentioned in the auction as:

We believe the 3-43 dated Rock-Ola barrel to be original to the Carbine. Interestingly, there is no Rock-Ola mark on the side of the gas cylinder but there is a letter mark on its front.

Here a link to the auction:

I'll give it a few days to see if anyone has any info....
Or curious/leery of it like I am.
Couple days and I'll pull a few RMC barrels to compare to.

Seth would call it a fake, right?

Yes Dave Old Seth would say It's a Fake!!!

Very Early Rock-ola barrels were marked with an R in the same position on the gas cylinder . Could it be an R ?

Could it be an R ?

With it blown up 250% it still looks like a B to me, but maybe is a R.
I sure waste a lot of time being curious.

[Bruce McAskill]

Sure looks like a B to most of us I think. And besides you have plenty of time to be curious as your retarded now like a lot of us. No more painting for you Charlie.

B&P Motor Sales didn't stamp with just a 'B'. It was 'BI' on the swaged gas cylinder.
Apparently, Rock-ola didn't date their barrels either.

Apparently, Rock-ola didn't date their barrels either.

Rock-Ola Dated Barrels up to 6-43 . The earliest I have seen and have is 11-42 on a 16629xx

That is definitely a B on the gas cylinder, maybe a light strike on the I, so light that it is missing? According to WB Inland sent 2215 gas cylinders to Rock-Ola in 1943.

Thank You RC

According to WB Inland sent 2215 gas cylinders to Rock-Ola in 1943.

Thx for the leg work Wayne , though we have no way to know if Inland sent their own made gas cylinders and or some from the Sub Contractors who also made Cylinders for Inland... like BI, RI, SI or WI.

Now I've been looking over the ROCK-OLA stamp on the barrel in the auction above and question it.
A few things jump out at me when compared but I don't want to say just yet.

Sorry I don't have the skills to do a side by side comparison pic.
Maybe USGI BOB will help if he stumbles by this.
