    Hello
    Unfortunately I don't have photos inside the fighting compartment of Archer. The nearest equivalent is from the Centurion Mk 3 manual printed in Bill Munro's The Centurion Tank (2005) which gives the idea of the recoil guard. It is bolted onto the unrecoiling parts of the cannon and the breech is inside it.

    One can also try to figure out the fastening of the recoil guard of the the 17 pdr in the Firefly (the white parts belong to the recoil guard) from the photo in the chapter Test 12 from here http://worldoftanks.com/en/news/21/The_Chieftains_Hatch_Firefly3/

    Of course if the safety device in the Archer is only a deflector shield (designed only to catch ejected shell cases), then it is difficult to take sides but that system would have been inheritedly dangerous and when firing the cannon elevated the recoil would have been fatal to driver's back rest if it was not possible to push it down.

    I haven't seen any primary source reference to the driver having to vacate his seat during firing, so it might be one of those cases where there is only evidence of absence, i.e. no original document is going to say "the driver is safe to remain in his seat when firing the 17 pdr."

    Considering the vast pile of BS that attends British WWII tank design (e.g. "incurable" Covenanter cooling, Challenger steering, 15mm Besa "whip") it wouldn't surprise me at all if this is yet another myth.

    I tried to find out photos of the breech end of the 17 pdr of Archer but no avail. The best I found were photos on 1:35 plastic scale model

    if accurate they imply that Archer had a proper recoil guard and so IMHO the driver could stay on his seat during firing.

    Hi,
    Below is a photo of a document dated April 1945. Various Anti-Tank units were visited and discussions had about what improvements could be made to the vehicles/units.

    It looks like the driver could stay in his seat when the gun fired.

    One of the things asked for was a collapsible driver’s seat as the current seat was fixed and if the driver was injured/wounded it was hard to extract him.

    Only decent photo that I could find showing the breech/seat was of a model being built.

    Regards

    Danny

    Excellent stuff Danny. Thanks for posting. I've ordered the Valentine SPG handbook posted above so will post any relevant info from when it arrives.

    This is an old P D Dyer plan from Bellona. Clearly the recoil would only reach the driver if the hydraulics fail.

    Clearly a shorter man would be preferred for the driver role. Off topic but were there height restrictions for British tank crew?

    Hi,
    Nine seconds into this film and you can see how much recoil there is inside the Archer. Blink and you will miss it though.

    The prominent RED on the ammo boxes in the first scene suggests they're firing the reduced charge HE, so the recoil probably isn't as fierce as normal, but it does give a good impression of the limit of its recoil.

    OT but still AT: later on, there's a nice shot of a Loyd carrier with the 6-pr's side shields mounted on the side - not seen that before.

    Think that footage is of a "pepperpot", i.e. every available gun firing during a barrage. This seems to be what Archers were mainly engaged in during this stage of the war.

    I have seen it a few times and I remember wondering what they were but never bothered looking too deeply into it.

    However recently the exact location this burning carrier at Fontenay is being researched and the large dark object difficult to explain away

    I was just trying to figure out what is was when I remembered I viewed this film this morning and saw the plates on the side of a carrier so I came back over to re-view and found another reply had explained everything.
    I believe the dark(ringed) object is one of these plates and the small triangles at the top are the same as can be seen on the bottom of the plates on the Goch film.

    Opinions?
