WTB: Oigee Reflector Sight (WWI collimator gunsight)

[Todt_Von_Oben]

If it's okay to post here looking to buy something, does anyone know of anyone in the antique aircraft community who might have a collimator gunsight for sale?

 

I'd like one for my D7F simpod; purely ornamental.  I've seen them for sale online but don't see any available at the moment, so I'm putting the word out among folks interested in WW1 vintage aircraft.

 

Thanks
