What is this, 2?

[SAPPER]

Just found this on EBay but have no idea what it is but if it could be useful for the Metheringham tower restoration and it is airfield related then I might have a flutter.

Any ideas?

Look like it's for testing/aligning the beam of the lamps, kind of like what they do during your MOT.

My guess is it's from the factory and checks for distortion of the beam caused by a mis-formed reflector. QC check before being sent out.

Gut feeling is this isn't an airfield item per-se.

Have emailed the seller re further info. I haven't a clue!

I was thinking along the same lines. Approach lights are set at a particular angle, so upon installation, some one must check the angle.

That piece of kit is similar in a way, to the checking equipment used for checking the old VASI's and later the PAPI's.

Just a thought.

Had a reply from the seller - the large silver object is a lamp made by GE. I therefore don't think it's a passive device for aligning ground-lighting fittings, and I don't think it's WWII origin. Could be wrong :wink:.
