These planes were built and 'hangared' at a farm in the Big Coulee, south of Ryegate,
Golden Valley County. The photos were in an envelope labeled Tom's Aeroplane.  

One, a 1932 Pietenpol Air Camper, belonged to Henry G. 'Tom'  (b. 1849, d. 1948) 
and it is now on display at the Paugh History Hall in the Museum of the Rockies, Bozeman, Montana.
