German 21cm Howizer 1917

[Tmine35]

I found recently this powder container.
Sweden purchased in 1918 12 howizers from Germany, they were developed from 21 cm H 10 and called 21 cm H 17.

Sweden sold to Finland 4 guns with ammo in 1939.

In container fits nicely a brass case for 21 cm H 17: 210 x 232 x R 236

However I wonder that the container is very long, 450 mm high. I have a Finnish manuals from WW2, in one page they say that powder pouches are 4, total weight 3670 g, the other page says that 9 powder bags, total weight is 5420 g. In manual pictures show that all pouches fit in case.

So, why this extra length? Or is the container for something else? The container looks very much German, but has no markings, except paint markings on lid.

Does anyone have a manual for this gun, or 21 cm H 10?

Yes, they exist in brass and steel. Brass pretty rare, can't remember ever seeing a steel case.

If this is the usual 21cm case in brass then I have seen a steel case but was a bit corroded so I did not really need to buy it.
I thought steel was scarcer but $200 was too dear at the time.

200 euro for the shorter 6305 steel case is the deal of the century. For the longer Mrs 18 it seems very steep indeed.

You have me worried now as I assumed it was a WW1 steel case 21cmx233R. I did not read the base stampings well due to corrosion pits.
This was about 5 years ago so long gone to somebody.

My century deal was about WW2 or interwar steel case with number 6305. WW1 steel cases are also pretty rare but at least I have seen several!

You could make the difference with the primer size ?
