WW2 RAF 3-inch filling

[Brennan]

Does anyone know what the filling weight is on the:

Shell, High-Explosive, 60 lb, Semi-Armour-Piercing (No.1 Mk.I specifically if possible)
Shell, High-Explosive, 60lb, Fragmentation (No.1 Mk.I specifically if possible)

I only have two sources and they're conflicting. If anyone has something definitive that would be great.

Thanks.

Whoops, and I also have a discrepancy on the diameter of the:

Shot, Armour-Piercing, 25 lb No.2 Mk.I

Thanks again.

Hi Brennan,
My 25lb AP measures 86.6 mm or in old money 3.41" if that helps
Will check on specs for the 60 lb but they are probably from the same source as yours.

This is from the Op 1665 British Explosive Ordnance, I dont know how acurate it is.

Thanks guys.

No slam dunks but it definately leans me toward one set of figures.
