You guys have been great with information on these has been great. Finally have some more information.

I opened them up today and this is what I found (see photos).

Not Chinese or Israeli knock offs. Still looking for information on the chassis, lense and tubes.

I have 2 / L3 EOS Model M890-1603 intensifier tubes, within 25 in serial numbers so likely manufactured on the same day..

Can anyone tell me anything about these tubes. Also does anyone know what front lens these have and are there any replacement lenses front and rear? How about o ring replacements, electronics upgrade for the chassis, etc.

Thanks again for your help!
