mk1 25 pdr barrel detail??
Can anyone post detail of the breech end of a 25 pdr barrels? I am interested in the method by which it attaches to the breech ring.

Rob,
The manual details the method of attechment of the barrel assembly to the breech ring: The barrel is loose within the jacket. It has a flange at the end to prevent logitudinal movement, and two grb screws to prevent rotation within the jacket. The jacket has an interrupted thread that corresponds with a similar thread inside the breech ring. The jacket and barrel (the barrel assembly) is inserted into the breech ring and turned 1/8th of a turn to engage the thread fully. A screw secures it in position , and a stop screw prevents the barrel from being rotated more than 1/8 of a turn. Mike C |
Thanks Mike
The 2 barrels that I found floating around in the dustbowl would seem to match what you describe. I was thrown off by the fact that the barrels themselves did not have the usual interrupted thread found on most howitzers, but rather a single flange with two cutouts on it. The barrels were both marked from SI (Sorel Indistries I presume) and dated 1941. |
Rob,
Just thought I would post these pics of a barrel I removed from a gun a while ago, if it helps ! Rob................rnixartillery. |
Yep, that does it nicely: the barrel assembly consisting of the jacket (the bit with the interupted thread and screw holes for the counterweight), and the barrel itself with the flanged end inside the jacket.
I gather from his description that Rob found just the 2 x barrels, without the outer jackets. Mike C |

Rob,
Here is a photo of the 25Pdr. barrel, sans sleeve. Perry |
Yep, that is exactly the chamber end of the barrel on these two. They were laying on the ground in the dustbowl along with a bofors barrel. They have now been moved to the paved compound, and I'll get some grease onto them.
I found a barrel jacket a few years back along the lines of what the 25 pdr has, except smaller. It always puzzled me what it was for. I'll post photos when I get back to that yard again. |
