BIG scope

bearcatter · 01-05-2018, 11:53 AM

Bought models of the Boeing P-26 fighter with my Christmas eBay gift cards. I'd never given much thought to old aircraft sights, and looked this up.

It's an Aldis sight, about 30 inches long and 3 inch I.D.. No magnification, but on some planes it was 2X. Four lens groups. No reticle, just a dot with a circle around it. You got a lead on a target crossing your path by firing as it entered the circle; the size of the circle was determined by a set target speed, in this case 200 mph. If the target was much slower or faster, good luck.

The British developed it near the end of WW1. It was replaced by reflector sights in the later 1930s, which got us through WW2.

I love the snazzy old paint jobs. Only P-26 still flyable, restored to markings of March Field, CA:

Models; Wheeler Field, Pearl Harbor; and Selfridge Field, MI:
