This is cool stuff. VERY cool! This flyer is presenting the specifications and promoting the exploits of 1939 Beechcraft 18S, NC19482, one of six built. (Parmerter p35) It is the first "Beech 18" with the P&W Wasp Jr engine, which we know as the '985.

The 18S is covered by FAA Aircraft Specification 710 (pdf), which also identifies it as an Army C-45C.

I'm not sure if some of these numbers were created by the engineers and test pilots or by the marketing department! When you look at that 12,300' single engine ceiling, bear in mind that it had constant speed (non-feathering) propellers! And not many Twin Beech jocks could get it off in 710', no wind, at gross weight either!

I suspect that the figures written on the cover were prices for an 18S with or without some options.

Parmerter covers the 18S in detail starting on p53.

Note at the top of the right hand column, that when you had skies on, which meant that you didn't retract the gear, you could put an additional #100 of baggage in each nacelle. A fascinating concept!

Among other things, standard equipment included two 3-minute parachute type flares and Moonglow type instrument lights. Wowzee!!

Two of the five 18S’s were impressed by the USAAC, to become UC-45C Expeditors. They were cn 292, NC20756, which became sn 42-53510, and was later with the FAA as N20756 and NC39; and cn 316, NC2500, which became 42-22247, and was later sold to become N79911.

Where is the "Garmin?"

Note that an artificial horizon and directional gyro were not standard equipment, but spaces were provided for them. These were the days before we had so much smog and there were many more VFR days.

This flyer says the gross is #7850, but Aircraft Specification 710 says #7500 for both the 18S and its successor the B-18S.

Now THIS page gets my attention. It says that with eight persons on board they took off from Medellin, Columbia; shut one engine down at less than 300' altitude; climbed to more than 10'000 feet; and flew the 160 miles to Bogota. It says that "Flights with full loads were made at altitudes up to 12,500 feet with only one engine operating."

All of that, mind you, with constant speed props (and the dead prop windmilling?), and probably 87-octane fuel at best.
