Last Saturday was the British ECRA meeting at Bisley and I was able to pick up a couple of items: a No 731 (Kealey) fuze and this 2” Mortar. There’s nothing particularly note worthy in respect of the body. However, what struck me was that it is fitted with a Transit Plug. As 2” Mortar were not supplied un-fuzed, this plug was presumably for use in the filling factory to retain the filling (Baratol loose powder/granules) prior to the fuze being fitted, though I would have thought there was an easier way of doing it.
The plug reads “42 BI – 1.77” – No. 1 – IIE”

Tim, was it not the case that all HE mortar rounds (2", 3" and 4.2") were shipped to theatre with transit plugs, and then fuzed in rear area Divisional dumps and depots for issue to the front line? I might well be wrong, but British policy was not to use fuzed HE munitions from factory - hence the tortuous post war development saga of the L2 HE hand (and rifle) grenade. Maybe AE501 or Bonnex can clarify.
But a fine transit plug - is the BI monogram for British Insulated Cables?

Tom,
I think this explains it -
Plugged Rounds
Fixed Q.F. Ammunition and Mortar Ammunition is sometimes issued from the factories fitted with plugs in lieu of fuzes when the latter are not yet available. These are placed temporarily in a plugged series but they are fuzed and properly Batched before issue to Units.
Ammunition Bulletin No. 36
Yes, it is British Insulated Cables of Preston, Lancashire. Who merged with Callender Cables and Construction Co., in 1945 to bring us "BICC" - British Insulated Callender's Cables and has now become "Prysmian"
Further research shows that that correct description of the Plug is "Plug, Fuze Hole, 1.77" No.1"

I have looked at this under high magnification and if 42 is 1942 and and it is fuze related I would say that it is No IIE, with fuze marks being in Roman numerals until 1945. (Inspectorate of Armaments Woolwich)

AE501,
It proved very difficult to photograph. There is actually a "1" after "No." Making it a No. 1 Mk IIE

I take your point. It did not make sense that 'No' was in its box without an actual number.
While I cannot make it out clearly I can see that there is something there and that it would have to be pretty thin in the space left, which is probably a '1'.
