    Heres my 14lb practice cem round which has hit something quite solid. The cartridge with red band found still inside and the bore is mint rust free, the round still has the logo on the side. I think this must be a Home Guard pickup and taken home as a memento.

    That's in much better condition than min, which is severely rusted, and the tail is buckled.

    Got my book today, had a quick look before getting stuck in. So much information and detail to take in, well done, looking forward to reading this.

    Thanks!
    You got yours before I got my gratis copies then :p

    Please do hurl abuse, offer feedback or ask questions. I've been using the feedback to improve the books as I've gone, for example von Poop moaning about the lack of index, so I put indexes in just for him.

    As a slight bump...

    Tomorrow I'm giving a talk for the Royal Armouries on the PIAT:
    The PIAT

    It's entirely free as per usual. You need to book however, and they'll send you a link before it starts so you can join in via zoom.
    A Q&A session will follow the 30-35min (depending on how much wittering I do) talk.

    I have read the book, very fascinating, keep up the good work. Shame your talk is not at the Royal Armoires at Fort Nelson, The PIAT is a fascinating weapon, they used them a lot around the area i live during the war.

    Thanks for the compliments!
    Could I beg a favour? If you got the book from Amazon, can you leave a rating or review. I don't mind if its a bad review either. I use reviews to find out what people do and don't like, so I can improve subsequent books (for example von Poop complaining about no index in my first book, indexes have been included from there on in). For some reason, there's just no one reviewing this book compared to previous works.

    I did have a number of in person talks planned but CV19 sort of inserted a size 12 into the plans.

    Unfortunately i didnt get it from Amazon, but i will post a topic on the BOCN forum for you as i think its such a good read and full of information that the forum members there need to know about it.

    On the subject of Spigot mortars, a friend of mine recently got a 14lb practice round where i noticed a sleeve fitted on the spigot shaft just in front of the drum fin as a distance space to stop the drum from moving up the spigot. Were these fitted as mine doesn't have one or is this some unofficial modification, see photo just above drum with a slot.

    No worries, and thanks. There's already a BOCN thread:
    Defeating the Panzer -Stuka Menace. David Lister

    That's the 15/20 prac, which was designed to be re-used. (it's also one posted on BOCN, IIRC, I've used a screen grab of the image in a lecture).

    I've just checked my 15/20 and it has one as well.I'm not sure what the purpose of the clip is. But the tails were known to split, maybe that is where they were splitting and this might have been re-enforcing to prevent that? But I would have expected the tails to split further up the tube where the pressures were higher.

    I don't think its the pressure but the recoil force splitting the drums, not sure if the drum would move back or forward under recoil, it would certainly move forward when it hit an object, the drum splitting was most probably caused by its very light construction of having the thickness of the fins doubled up with two thinner sheets to make up the thickness.
    A spacer would make sense as my drum is loose on the spigot body between the rear where the circlip goes and the next step in the body and moves up and down.
    Not sure if a fresh factory round would have a tight fitting drum on the spigot but after firing a few times the drum loosens up hence the spacer. I also noticed that the 20lb projectiles have this spacer but much shorter. I would also assume that the main spigot body would be the same for both types in manufacture. I think there is a slight taper in the bore of the spigot body tube for ease to remove the spent cartridge.

    I meant tail tubes, when I said tails. Not the drum tails.
