I recently learned about this museum located at the Schuylkill Fair, so I stopped by to see what was there and was pleasantly surprised. They have an operating steam powered sawmill, 40 HP Bessemer gas engine, a pair of old wood lathes, several hit and miss engines, two stationary steam engines, and a lot of farm machinery. It is worth a visit for anyone visiting the Southern Field. Their website is here:
