Seller notes

United Instruments Inc. 4000-0-4000 FPM vertical speed indicator instrument core in good physical condition. Nice shape showing signs of ordinary use and years of storage. Last visible repair stamp is from Nov 1995. Seems to work but is sold as a repairable core - as pictured and AS IS and cannot be returned. From a smoke free home and shipping is $12.99 for USPS to 48 states. Thanks for looking!...
