Vintage Metaframe Aquarium Bon Air Air Pump NOS in box!

Description

Vintage 1960's/1970's Metaframe "Bon Air" air pump complete with box and instructions. This is NOS (new old stock) found in a barn and around 50 years old! The air adjustment screw on top of pump has some rust from humidity of sitting in a barn all those years but this is essentially a new aquarium air pump! Check out the photos and ask any questions. Thanks for looking!
Note: These pumps are 50+ years old hence the diaphragm (that pumps the air) is probably cracked or compromised at this point. They are being sold as decorative Metaframe (very collectable) antique and not working air pumps!!
