Something that I have noticed is that on many models of the M113 (particularly in small scale),
the driver’s periscope housing (on the outer face of the hatch) is represented as a hollow section,
with a direct space between the front and back. Is this an error, or was the actual periscope not
always installed?
Paul
This is not an ordinary periscope but the drivers night vision device.
HermannB, I never realised that. So, can it be removed, so leaving an empty space?
Paul
No Paul, it is covered. I send you a pic of a model part on Monday..
Looking forward to seeing this as I’m preparing an M106 for being carried on a trailer.
The info will be greatly appreciated.
Someone else wanted M106 photos. I recently photographed one. I’ll post soon.
Let me copy-and-paste the reply I posted on Missing-Lynx to this same question you asked there:
Hard to photograph because of the manual’s thickness and me having only two hands, but here’s the intro to M113 periscopes:
This is what the M19 looks like:
And here’s how to install it:
No need to say thanks? 
HermannB & others who have responded, Many thanks for your very helpful responses.
