Just a simple question, that I have yet to find the answer to; who was the WWII-era manufacturer of the original N-9 Gunsight? I'm hoping someone here may know. I have found a few photos showing the manufacturer's label on the side of an N-9 sight, though I can't quite make it out. It seems rather difficult to find any photos of great quality, of the N-9 as a whole, on the internet - it must be a very rare item!

Thanks in advance for any help you may be able to provide!

This is the closest I've been able to come, though either I am very dense, or the manufacturer's name is as hard to read/understand as I think it is. The first part looks like maybe "Robinson" or "Roginson", at least that is the only thing that would seem correct, and I can't quite make out with what the rest should be. (note the AN government ink-inspection stamp)

Robinson-Houchin Optical Company Columbus, Ohio

They were still in business as of 1965 per Google search

Those Gov. Inspectors sure used some stout ink!

Awesome, Spanner, thank you very much for getting my question answered! Definitely not so hard to see it now. ; )
