Mar 29, 2023 · Need instructions on disassembling a M53 Mortar Fuse. What are the steps and procedures? I have one that is missing the brass safety pin and have found a replacement that I wish to install.

The M53 Fuse is a delay fuse used to effect the functioning of rounds fired from the 81-mm trench mortar. It is normally used with heavy shell where penetration is desired. This fuse will fit any of the "M" series of shell; however, it is only authorized to be …

It was a waste of one element to use a selective fuse on trench mortar shell, because it was known before the shell ever reached the firing point what action fuse was desired. The M52 P.D. super quick-and the M53 P.D. delay are standard for issue and manufacture (S as M).

Feb 25, 2024 · I located this exceptional original Yellow 1940 dated 81mm M56 Mortar body to attach to my correct M53 Mortar Fuse. I collect early yellow HE, Inert Ordnance, so this was kind of a "Grail" item for me.

This is a totally genuine United States military WWII produced SHELL, M43A1, with an inert aluminum fuze. The fuse base unscrews to allow the explosive chamber to be inspected.

The M52 is an instantaneous on contact detonation fuse for fragmentation or anti personnel effect. The M53 has a tenth of a second chemical delay built in.

The VT fuse was used to destroy air targets, Excalibur is used against ground targets to minimize collateral damage. Here's another fuze photo, contributed by Chris, who provides the following background on it:

The body mechanism therein is identical with that of M52 series fuzes, except that the guide pin in fuze M53A1 serves as both a lock pin and guide pin. No information about functioning. Description The fuze is a single action type with a direct action firing device.

These replicas make great toppers or projectiles for your brass casings you have collected but can't find a shell to put in them. I do accept requests and can design custom artillery and tank shells for whatever project you are working on. Nice fuze, looks great on the shell. Thanks for working with me.

PROX fuse, used with 76-mm naval artillery projectiles. Impact back-up and self-destruct feature. A switching ring on fuze, allows automatic setting in the breech, prior to firing.
