Odd Linkert M35TP Carb.

Can anyone identify this oddball? I'm thinking that it's for a barrel racer??

Now that I found all the pics and zoomed in, Craig,

Its a normal 1948 (Panhead) M35TP that has been cut'n'pasted to rotate the manifold flange for some reason, with the "toe" support our only clue; The idle gallery has been piped from the vertical passage plug to the bleeds relocated to the top of the body.
(This precedes the accomplishment of a horizontal shaft by the DC series by a decade, increasing efficiency by supplying the separate cylinders more evenly.)

But this piece insinuates a motor rotated ninety degrees. But then again, I 'spose whackng a manifold's flange would be even easier (even I could do that), which means this "prototype" may have been created solely for the advantage of the horizontal shaft. (A patent search may be fruitful, if anyone has the time...)

The internals are inscrutable without disassembly, but the venturi appears smaller than 1 1/8".

The signs of brazing just ahead of the throttleshaft bushing bosses, in addition to the piping, took a lot of patience; Its a great piece, and will take some time to figure it out, Thanks for sharing!

PS: Sorry,..

I can't help myself.

I guess that I misspoke on the barrel racing. I was thinking of the Wall of Death type of racing.

Y'er diggin in deeper, Craig!

"Barrel" carbs were a design for racing, but not a kind of racing:

I'll bet the first heats of a Wall o' Death race were a mess!

PS: At least "barrel racing carbs" actually existed; I'm still looking for a "suicide shift"..

Thanks Cotten. Interesting carb! But I'm back to square one. What is and why?

The innovation of a horizontal throttleshaft, Craig,

Wasn't as easy as it seems!

Moving the idle bleeds was the real task, and that's why this smells as much like a prototype as a 'wildcat'.

Nonetheless, it is this achievement that marks the divide between archaic and modern American motorcycle carburetors:
Instead of having the idle bleeds biased to one cylinder on the side of the bore, they are split evenly between the two at the top. The result is easier tuning, better fuel mix and burn, thus more power, and better mileage.

....Cotten
PS: Without the associated manifold, we may never be certain of its application.

(Note also, that 1948 manifolds were of silver-soldered construction, and the easiest of all to modify!)

Great observation!

Its a great piece, Craig!

Is it in your possession?
