It is a awesome to see the attention being put into these different variants of the Stearman. The civilian modified version looks gorgeous - I love the raised turtle deck behind the rear cockpit and spats. That model will be a great base for a number of repaints of other Stearmans flying today in similar configuration as well.
One Stearman I'm quite familiar with is the N2S-1 that was restored a few years back by AirCorps Aviation for Paul Ehlen/Wings of the North and is one of five known surviving that was flown by President George Bush Sr. when he was undergoing his initial pilot training in the Minnesota winter of 1942/43, based at NAS Minneapolis. It was restored with absolute accuracy in every detail, including no avionics and no way of starting the aircraft except from the outside/original method - hand crank, primer and starter-engage on the front cowl. The aircraft was operated that way for about a year, only using a hand held radio to communicate with atc. After a year went by, and the aircraft had won awards, they installed some basic modern radios hidden inside the data case in the aft cockpit. I believe it still remains one of the few/only Stearmans flying today that still requires another person on the outside to start it (most have been configured now to have an electric starter with a switch in the cockpit), unless that has since changed as well.
Here are a few photos I took a few years back of that aircraft:
Note the black tape masking the fuel pressure section of the three-in-one engine gauge, which is a detail that was copied from the original factory production which calls for that to be done - since the fuel pressure part of the instrument wasn't used. In this photo, other than the modern GPS mount, everything is stock accurate to original N2S-1 production (I also have photos of all of the different stencils all over the airframe, if interested - for instance, every strut has a unique number stenciled on it, corresponding to the same numbers stenciled on the wings and fuselage where those struts mount, and every fabric surface has a stencil with fabric specifications and dates when applied).
Here you can see the limited Becker avionics installed inside the data case, so when closed, it otherwise looks completely stock.
