N-3C Gun Sight Reflector Glass Dimensions (1 Viewer)

[VintageIron]

Hello and thanks for taking time to read this.

Does anyone know the dimensions of the reflector glass for the N-3C gunsight? I would also be interested in new old stock, or accurate reproduction glass, or, as the title says, dimensions so I can make my own.

Thank you!

If you have the glass holder, should be pretty easy to scale it from here:

Very nice N3B body with rare early war sight head. This one has replacement glass and replaced cross bars (the original rusted off). I have never seen this short variation. It was probably used on the

Thanks for your reply, I have an N-3C gunsight body, but don't have the sight hood that holds the glass. I'm a machinist toolmaker, and have the dimensions for the sight reflector hood, but the details for the glass are omitted from the drawing I found. I do know the drawing numbers that were on the data plate of the sight, do you know if that information would be in the National Archives?

This might help. It is from Aviation Archives

Could you please send the dimensions for the reflector that you have? I am trying to recreate a reflector for my sight, but I have not been able to get a solid measurement. I plan to initially 3D print until I have time to actually fabricate something.
