I am not privvy to what the value is however I have no doubt it will have a few zeros on the end 🙂 due to the rarity and provenance.
Wondering how many original complete instrument panels come up for sale outside of Auction houses in the past 10years, Can anybody say?

Now with the winter almost over I have started again to help out with sorting out surplus parts etc .
This is an original Spitfire Instrument panel, first produced for a Mk2 spitfire but was in the end fitted to a CBAF MkVb until it was replaced by a brand new panel in 1991, so yes the provenance of this panel is known.
It is fitted with so many original instruments including the RPM gauge to merlin drive cable, its easier to say what is not, Fuel gauge label, the flap lever assembly is a new high standard replica, the boost button rear plate is replica, both button covers are also replicas , the Nose UP/Down gauge is an original but has been put inside an airworthy case replacement and is working. The time of trip clock was from a Sea Gladiator and obtained from Malta.This also comes with an original rectangular BFP , sadly did not have time to photograph this.
PM me and I will give you the sellers email so higher resolution photo can be sent to any interested party, serious offers only please (No timewasters thanks),sorry but UK only as the panel will have to be collected in person.
Regards
Jason
