Unknown 172mm / 7 inch APC projectile.

[DEADLINE222]

I have been through every TM and OP I have at my disposal and have came up empty handed.

My search placed emphasis on US Navy or German because of the dual rotating bands.

This projectile is armour piercing, ballistic capped.

It is boat tailed with a solid base. Heavily pitted with no markings I can see.

The two rotating bands made from copper with both having different shapes. They are solid and do not have under cuts like naval projectiles. No markings to be found.

I see no bourrelet, but it could be under the multiple coats of paint.

The projectile weighs 120 pounds.

It is 32 inches tall.

It is 6.8 inches in diameter, or 172mm.

Hello,

Have you thought about a German 17cm L4.7 ?

Regards



Maybe this one

 

[Yodamaster]

Are you sure it's an AP projectile ?

Otherwise, I'm completely agree with MinenAZ16, your projectile is VERY similar as the german kriegsmarine 17cm Spgr L/4,7 Kz (m.Hb) with the E.Kzdr.F.Spgr (m.Hb) !

It looks like every 17cm that I've ever seen. There are a lot of them in the U.S. The harder part to find is the brass cartridge case.

Hey now.

Just because you have a room dedicated to this particular projectile, that dose not mean anyone else is not aloud to have any fun.

I'm really confused about your comment. There are a number of postings about this projectile on BOCN, about how the guns were brought to the U.S. for evaluation after WWI and all the projectiles that came with them, and how they are quite common. I've had at least 3 over the years and US-SUBS has seen them all over, and owned them. For such a modernistic German projectile from WWI. they are common here in the states. And, I would never dedicate an entire room to anything so common. I was just stating a fact. I'm sorry if you thought it was rare and I burst your bubble. Its value is in the eye of the beholder. Maybe taper off on the caffeine?

Feel free to have all the fun you want, however you want.

There is actually a much rarer similar projectile, the 15cm.

Here are found the 15cm much easier than the 17 cm.
just 17cm"lange tuur" cartridges are easy to find here.

Dude.

I was just playing; trying to make conversation.

You should have posted those links initially. I love that all yellow paint scheme.

This image is of the back side of the projectile. Does this mark mean anything noteworthy?

On the reverse side under the numbers, I can see a faint Kr.

Is this Krupp?

I also see a faint 08 or 18 to the lower right of the Kr.

Is it known where the factory is/was that manufactured this projectile?

 

[HAZORD]

I'm thinking the crown with the M is the maker's mark.

 

[joery]

the crown with the M is a marine mark.
kr = krupp
