Granatenwerfer 16

Finally got a Gr.W. 16 and IT WORKS!!!!!!!!!

The spring is still strong - it shot a wooden dowel rod a few feet. Unfortunately there were some pieces missing though the Schieſsstockkopf (shooting stock head) and Schlagbolzan (firing pin) and possibly the Zwischenstück (spacer connecting piece) between the shooting stock and the shooting stock head.

I found a guy in the state next to mine who had two Wurfgranaten 15 he'd sell me - one in relic condition and one beautifully restored.

After the first cleaning I gave it a better, second, cleaning. Nothing abrasive, just a mix of vinegar and water and a very gentle scrub pad. I was surprised to see how well the shiny parts cleaned up!!!

When it first arrived you could only see two red marks on the arc - now you can see three. You can even see a red mark painted in the slash forged in the handle.

Not sure what the off-white spots are, they look like paint splatter. I'd love to get rid of them but am afraid of ruining the paint underneath.

As stated earlier all the missing parts that were missing in order to make this puppy work have been obtained. The Schieſsstockkopf, shooting stock head, was machined by a guy on the east coast that has made a couple in the past - it looks perfect! The Schlagbolzan, firing pin, is an original that came out of a Gr.W.16 collection in California - one of the most complete collections known.

Now that those pieces are here it became obvious that at some point the Gr.W. 16 went under a redesign from the one shown in the manual. The new design was made so that the Zwischenstück, spacer connecting piece, was no longer needed. Not sure if this came about as a way to save material for other uses or as an answer to have extra parts which would lead to extra chances for loss. It could have been a combination of both.

When I first tried the pieces together the pin was sticking in the top cap when I would insert it by hand. It was sticking to the point I wasn't sure if I could remove it at times!!! I checked the measurements and they were a perfect match. so I polished both parts. The pin moved freely by hand, but when attached to the Gr.W. 16, and fired, the force of the spring rod jammed the pin into the hole - it would not fall back down into the shooting arm. It was suggested that the force of the propellent would push it back down but I knew that it was suppose to drop down under it's own weight.

Taking it apart again I took a closer look at the shooting stock head. On closer inspection there appeared to be the tiniest sliver of 'something' that was coming from the inner shoulder up into the hole the pin went through. The only way I could see it was to shine a bright light through it and use a magnifying glass. Using a small drill bit of the same diameter I stuck it in the hole and twirled it with my fingers for a few seconds. After this it was gone. After reattaching the parts I tested it and it worked perfectly!

The pin punches out, then falls back down, so fast I put paper over it to make sure it was working - the punch hole proves it!

I know a guy who has exact reproductions of the Wurfgranate 1915. I'm trying to see if the guy who made them for me can make one or two for me. They are powered by .303 blanks.

Hopefully I can get one of these repro and have a little fun!

Please check out my post in the "wanted" section in case you might have something Gr.W.16 related you'd want to part with.

Bear in mind that propelling a grenade with blanks is going to be just as powerful as using live rounds, the projectile of the live round in imbedded in the base of the grenade and remains with the grenade with the cartridge is fired. So as far as the force that the grenade is projected will be the same if it is a regular round or a blank.

congrats to your new Gr.W. 16 i wonder how it works :-k

Actually - it's quite simple! There is a powder filled rifle shell up inside the grenade. When it's placed over the 'spigot' (shooting arm) of the Gr.W. you just pull the triggering cord and the firing pin hit's the propellant shell just like a rifle's firing pin hits a bullet.

Nice piece, there is a fellow that brings one for the GWA in neuville, he makes his own very good looking rounds and uses .45 Cal blnks to launch them.

Do you know who it is?

You have a very interesting piece. It looks very nice. Good to see another one around, other than in a museum. :D

I also have one, that needs a couple of pieces. The T-handle and the outer piece that holds the granatenwefer at an angle.

Seeing your's makes me want to start to work on my own.

Regards,

Cliff
