Didn't Conroy propose a single-engined turboprop conversion of the O-2/Model 337 with a Garrett TPE331 in the nose and with the back end reconfigured to side-hinged clamshell doors like some C-119s?

Thanks for that. And for the nudge ... it prompted me to update, revise, and correct a few Turbo Dak-related postings.

Nice! Thanks for sharing.

Conroy Aircraft called N156WC its Conroy Super Turbo Three - because its was based on a DC-3S aka Super DC-3 airframe.

AFAIK, Conroy used the name "Tri-Turbo-Three".

They did indeed. Although the hyphens don't appear in many Conroy documents. Elsewhere, however, you'll even see 'Tri-Turbo-3'. Your photo shows the re-registrated N23SA but this airframe had been the original 'prototype' Turbo Three conversion, N4700C. It was further converted to Tri Turbo Three standards in 1977.

The Super Turbo Three N156WC mentioned in reply #244 can be considered as a second 'prototype' conversion. It was based on a DC-3S airframe (c/n 43193), hence the Super Turbo Three appellation.
