M10 Achilles sight dial
 

Hi what number sight dial should the 17 pounder in the m10 have ?

Mark,

On 15 Nov 44, 200 Armoured Delivery Regiment (British), sent a document to it’s subordinate units including ‘B’ Canadian Armoured Delivery Squadron, which detailed the current sighting devices for various equipment. The document shows British and American Periscopes, Telescopes, and Dial sights. There are multiple sections of the document, with the first sections being alphanumeric lists of the sights with the intended application, then there is a section which lists vehicles and details the applicable devices.

The cover page can be found here: https://heritage.canadiana.ca/view/o...eel_t12746/774

If this document is correct, then it appears that M10 3” was issued with US telescope panoramic M12A4 “if fitted”, but it appears that there was no dial sight issued to M10 17-pr.

Indeed, not all M10s had the mounting bracket for the M12 panoramic telescope. The dial sight was only for indirect fire and whilst some 17 pdr towed guns were modified late war to allow the carriage of them, they were only for indirect fire which is not the principle job of an anti tank gun.

Interesting the load diagram of the m10 17 pounder shows the storage for a sight but not what model?

That dial sight case takes a No9 which was the standard sight at that time. I can't find an image of a socket for a dial sight though....
