Honeywell Flame Protection Relay RA890F1288. This is a recent take-off from a system removal. I serviced this building for 20+ years, and installed this piece 5-10 years ago. This is not a re-build, came right from the Honeywell distributor.
Nice to have as a back-up, or you may have an immediate need. If you are reading this, you know what they cost new.
$80 + whatever freight you want.
PM me if interested- Thanks, Bob
