The smaller of the two wooden conicals uses a Cogent driver made by Steve Schell and Rich Drysdale but no longer produced.

As mentioned above it depends on the range you're after though I remember that Bill Woods, designer of the horns , used to say he liked the B&C DCM50 which was inspired by the old RCA MI-1428 - the improved development of which resulted in the Cogent DS-1428.

the OMA are gorgeous! Modern, industrial, artistic. Wonderful.
But conical horns, nogo. Lo efficiency, limited bandwidth, no CSD, strong beaming, HW-notches.... the worst of all.

But I totally understand one might gives optics a higher priority. I often do

So your saying they look good but performance sucks? If that's the case I may as well stay with OB.

efficiency: with a capable compression driver, still enough to match any but the most dedicated HE bass schemes

bandwidth: no worse than most horns, needs EQ because of constant directivity of course

beaming: ??? they display constant directivity dictated by the angle, Exp or Tractrix beams more. Driver or throat diameter will dictate when the conical horn actually starts to beam

Not saying they are perfect, no audio device is, but they certainly are plenty usable.

Good stuff.
I'm eager to see how you decide to mount the drivers. It's always been something with DIY conicals of wood that I haven't found a satisfactory answer to. I figure the the small drivers you are starting with might be easy enough to strap against the throat with bands attached farther up the length of the outside of the horn. But trying heavier bodied drivers like the old Altecs ,JBLs, etc., would be harder to make stable that way.
Bill Woods' answer was to terminate the throat end of the wooden horn in an aluminum casting, machined round at the last 1/4" and use a 1/4" thick mounting plate "donut" with edgewise set screws to hold it on to the machined casting once the drivers had been bolted to it. Doing the whole thing purely of wood though, that would be another story. Please let us know how it goes.

Oswald Mill is not conical even though it looks that way. Each leaf is curved inside to form a flare.
