I was asked to provide dimensions for the periscope handle and thought it a good idea to start a thread on all things periscope, most would be surprised at how complicated the periscope is.
anyway i will start with the handle.
flat bar 3mm x 19mm
external width 112mm
vertical height outside of base to joint 123mm
the notch to allow access to the pad screws is 96mm from the outside of the base and is 9.5mm across and 5mm deep
the locating pin is central on the bar and is 9.5mm from the the hole centre to the end
black plastic handle 95mm x 7mm x 18mm, the 3 rivet holes are 33mm centres
the tricky part that connects to the body of the periscope is best shown in the pics. it comprises a locating pin, a double round ended piece 45mm x 19mm with 2 holes (the centres of which fit into the centres on the periscope body) and another piece which runs in line with the main part of the handle, this part is welded onto the doube ended piece as shown.
the russians made a version of this periscope on which they used a flat piece of bar bent to fit with2 holes in it. simples
