WW2 US Ordnance Dept Spotting Telescope 4x11 deg

This lovely little scope gives an 11 degree FOV through uncoated optics with no reticle but I've yet to discover its exact use.

Since issued by US Ordnance, wouldn't it be some sort of high angle artillery scope?

That sounds reasonable Zbig but since I posted it, I've found out it's probably a heavy mortar sight. Have a look at this modern version;

M67A1 Sight Unit: Details
NSN: 1015-01-556-1178
P/N: SLB10821
General Description

The M67A1 Sight unit is currently used to lay the EFSS M327 mortar system for deflection and elevation. Lighting for night and low-light operations is provided by LED illuminated scales and level vials.

The M67A1 Sight Unit is comprised of the M67A1 Elbow Telescope and M67A1 Telescope Mount and is used on the USMC EFSS M327 (120mm) Mortar System primarily but can be used on all mortar systems

Field of view:    10°
Magnification:    4.0x

You are surely right, Niall, a mortar elbow telescope sounds most reasonable
