Any ideas on this Achilles wireless setup

[Jack Geratic]

Concerning the book, it does include footnotes at the end of each chapter for specific info, but none provided for the subject of the wireless.

The M10 and Achilles were based on the Sherman M4A2 hull, but were obtained to equip AT units which were part of the Royal Canadian Artillery. Regiments of course were assigned to both infantry and armour but they remained RCA. This may be a factor on how the assigned wireless may have been altered or converted once in the field.
