Terrific tonality!

Yessir, you nailed that one!

You're most kind, gents.
DWT - you & rmann certainly get credit for the inspiration.

Well done!

Very rich tones.

Thank You, Andrew. First yourself, then Tony Lockerbie recommended the steamy romance between HP5 & Pyro. At first I thought it was the only think that compared well w/ D76. Now, I find I don't want to run out of Pyro. What it does to metal is wonderful.

Love those radial engines and their cooling fins - really nice tones through out - well done

Yes, I'll toss in that for those in, or traveling in, the Northeast US, In Hammondsport, NY, in the Finger Lakes region (a worthy target for a lens in its own right), there is the Glenn Curtiss Museum. It seems in the middle of nowhere and from the highway, not very large, but ooo-weee! Radials, X-24 engines out of (B29s? ooops, no apparently not ...), which are works of art. And all sorts of stuff, not to mention (a reproduction of) the motorcycle with an air-cooled V8 (designed for aircraft use) that Curtiss himself drove to nearly 140mph -- circa 1907!

Tried unsuccessfully to find something on X-24. That museum sounds like a place to bring a truck full of film, 3 days food and a sleeping bag.

Well that is my term -- I forget its official name, but it was essentially two V12s stuck together with a gearbox linking the two crankshafts and the propeller drive -- one heck of a piece of machinery. I have pictures "somewhere" -- can't remember when I was there, so they may be electrocuted bits! Ah, maybe *not* for a B29, that appears to have been a twin radial -- total 18 cylinders!
A bit of Googling shows Allison made a "true" X24 in the mid-1920s; but the one stuck in what's left of my mind was a sort of fusion of two V12s -- could even be it was experimental, I suppose. "One of these days I'll find the pictures I took."
