Hi,
No official doc but as far as I know the diameter of projectile is close to 76mm (body) and 80mm on top and bottom (closing disk) so the mortar is close to 81mm.

Thank you, then the STOKES mortar tube may be 81,2 mm and the bomb 81mm.
For this reason the french bomb "BM" (Brandt Maurice) of 1918 could be used.

The diameter of the Stokes 3" bomb at the head and at the base plug, as shown on the inspection drawings, is: High 3.179", Low 3.175". The mortar tube is therefore a nominal 3.2" or 81mm.

Looking at your first diagram, so these (81mm and 60mm) are early Stokes? Or late Stokes, depending on your perspective. I note that the 81mm has atamped markings on the fuze adapter, PCM M17. Original? No fuze adapter is shown in the diagram.

Because these rounds are French (Brandt), 81mm Model 1918 and probably experimental 60mm (Kz11gr mixed french and british docs).
