While I like them, few seem to appreciate the boxy, often stainless steel trimmed pumps of the late 60's through the 70's. Is there a book that covers the different pump models? This would be for suction pumps that have mechanical computers, or even some of the digital electronic displays. I hope I am not angering any pump purists. To me they are more than scrap metal.

Antique? It's new to me.
