The following auction appeared on eBay, August 2015:
- Up for auction is a operational model of a Westinghouse single cylinder air pump made by Zimmermann Gmbh. The pump is about 30 years old, and I believe was purchased at the Nuremberg Toy Fair in Germany. Pump is 5.25" tall, and includes a sizable displacement lubricator. Please note that the drain screw on the lubricator has been broken and needs to be replaced.
- The pump cycles smoothly on air, and is set up to be a boiler feed pump rather than an air compressor as it appears to be. The original instruction sheet is included. The pump is mostly made of brass.
