This is an original World War Two  Douglas A-20 Havoc landing gear and flap position type  indicator gauge instrument. The gauge is 3 1/4 x 3 1/4 x 3 inches.  The A-20 Havoc was flown by just one pilot. Today there is only one airworthy A-20 Havoc. This gauge would have been used in many WW2 twin engine aircraft such as the B-26 Marauder, some B-25's, A-26 Invader, etc.  This item is being sold as a collectable.  Buyer to pay actual shipping.  AZ residents add 6.7% sales tax.
