what fuse is this?

[divedigger]

found this fuse in a 8" shell nose fragment. Has no face left but looks like a Schenkle, only with a big step. Any ideas?

Hi, Would you mind showing a pic of the head. Also, is there any indication from the shape of the fragment or where it was found if U.S. or CS.

Different for sure...what is the diameter at the threads and tpi?

[divedigger]

looks like 10 threads per inch, can't get a measurement on diameter, and this is what the top looks like

[divedigger]

another angle

10tpi suggest Schenkl.  Can you see any evidence of a safety set screw in the side (perhaps from the inside on the portions where the exterior of the fuse body is covered by the shell iron)?

[divedigger]

Can't see one

hmmm... the step makes it rather odd to me, lol....  not aware of such thing.

Mr Woodenhead I wasn't ignoring you but I don't really know where it came from, but somewhere around Charleston is as good as I can get it. Looks like a Parrott to me but I'm not an expert.

Mike I looked again and corrected my first post, the shell is 8", the fuse is somewhere around 1.175" diameter , is roughly 2.175" long(without the lip) and is 15/16 from the bottom of fuse to bottom of step

Sorry, I've been studying the CS field artillery projectile,s but I don't know much about the big ones. Maybe Jack B. or "Silent" Pete will chime in here. If no one else speaks up, then look at Chuck Jones fuze book and see if you can rule out Archer's percussion fuze.

well I took it to Richmond and Mr Pete George called it a Hotchkiss that was turned down on a lathe to fit this particular shell. Makes sense, we made mating parts all the time when something expensive didn't meet spec

Ah, good stuff!
