Torrey McLean Posted 4 July , 2020 Share Posted 4 July , 2020 Hello, Zil - Based upon size and weight, I consider these transport plugs to be for British shells larger than 18pdr field guns. I have found them in what I thought was a 6-in or 8-in howitzer position. If I'm wrong, I'm sure that other forum members will correct me.

ZIL Posted 4 July , 2020 Author Share Posted 4 July , 2020 Thanks Torrey, I have an inert shrapnel shell and fuze. ..18lb...the thread size is bigger...I ‘thought’ a impact fuze for an 18 lb had a 50mm thread but I stand corrected.This is a new area to me..like you say...there are forum members with knowledge on this subject.Regards Zil Link to comment Share on other sites More sharing options...
14276265 Posted 4 July , 2020 Share Posted 4 July , 2020 It is a combination of a Plug, Fuze-Hole, Special, No.1 MkIII (made by Howard and Bullough Ltd, Accrington) in an Adapter, 2-inch Fuze-Hole, No.2 MkII (made by Evered and Co., Smethwick). The adapter enabled a fuze with tapered GS thread, such as a No.45, to be used in a shell with 2-inch fuze-hole thread. Link to comment Share on other sites More sharing options...
ZIL Posted 4 July , 2020 Author Share Posted 4 July , 2020 Thank you 14276265, That is a most comprehensive reply...as I have said this is a new area to me...do you know of any diagrams/photographs showing this as you describe? This has really intrigued me!!!! regards Zil Link to comment Share on other sites More sharing options...
ZIL Posted 4 July , 2020 Author Share Posted 4 July , 2020 Thanks again 14276265, After rereading your reply and examining the item....the resulting photo is self explanatory...for me discovery and understanding.But what calibre shells would this have fitted.

14276265 Posted 4 July , 2020 Share Posted 4 July , 2020 The adapter was used in various HE, chemical, and smoke shell from 3.7-inch and 18-pr up to 12-inch. Most WWI era Land Service British shell were made with 2-inch gauge fuze holes, and HE shell could either take a graze fuze of the No.100 series of 2-inch gauge, or a direct action fuze such as the No.17 or No.44 of General Service 1-inch gauge with the adapter.

ZIL Posted 5 July , 2020 Author Share Posted 5 July , 2020 Thanks once again 14276265, Really appreciated ....I and I am sure others on the Forum now have a better understanding...indeed insight..into the complexity of such items. It came apart so easily after all years. regards Zil Link to comment Share on other sites More sharing options...
