I’m not asking about the Dallas TV show.
I’ve seen several engines with these initials or Serial number vibra-penciled in. Example JR 15. See photo
Engines I’ve seen with markings include OS 40 FP, HP Gold Cup 40, and Thunder Tiger 36
Thx for your help,
Jim Hoffman

It's "Jr.", not JR.
That's an engine reworked by master engine reworker Junior Samples.
You're welcome. H^^
;D

Roy Clark and Buck Owens were my favorite engine builders

Hi Jim
GUILTY !
JR is me, many of my very early motor I just use a serial number and my initials J R (James Randall)
That is one of my OPS engines you have there, and maybe is AAC special

BY the way I built that OPS in the late 1980s or early 1990s

Nobody can do an engine rework like Merle Haggard. I mean nobody!! H^^

Randy,
Thanks for solving the riddle.
The motor in question (in the photo) is a Thunder Tiger 36. It features an Aero Products spray bar, needle valve and venturi. SN JR 15 is on the bottom of the case.
Is this an early Aerotiger?

Hi JIM
that is not an Aero Tiger, or a Thunder Tiger, the engine shown in your picture is an OPS 40
As you can clearly see it is a center case with removable front housing, NO Thunder Tiger 36 was like that, plus the casting surface is OPS

Hi Randy, You are correct. The Thunder Tiger on hand has your venturi, spray bar and NV, but not the JR 15 marking. The photo is one of the three OPS 40 on hand. Two of which are yours. (JR 15 and RANDY 49)
The OD of all three OPS liners are visisble at the exhaust and are brass colored. I suspect none are AAC. How did they run? I don't recall many OPS powered stunters. Maybe some of the early piped models??

Hi Jim
They run well either way, as long as they have the proper size venturi, I setup a boatload of the OPS SPA RE 40s both AAC and AAC, They were the second strongest of the pipe 40 engines,
I ran them late 80s untill about 1993, then the PAs replaced them
People like Bill Werwage, Bob Hunt, Rob Hunt ,Bob McDonald, The BEAR , Frank McMillan, and dozens of other used the 40 SPA in their stunt ships
