scalled up maxim machin gun funny
Updated with the addition of 3,7 cm Pfeilgeschoss/granate (APHE-FS) and 8,8/5,25cm Pfeilgeschoss (APHEDSFS) More info and possible tests greatly appreciated!
I’ve seen some sources saying that the Germans called the 5,7 cm Maxim-Nordenfelt L/26 the “Belg. 5,7cm K.” Is this true?
No idea, but captured ammo had casings of belgian production and i remember that some guns were captured there, so maybe?
Fortress gun
In 1887 the Belgian War Ministry ordered 185 5.7 cm fortress guns to arm their fortresses including Namur and Liege. The 5.7 cm Maxim-Nordenfelt was a short 26 caliber gun and not the longer 42-50 caliber QF 6-pounder Nordenfelt naval gun. It was a typical built-up gun of the period made of steel with a vertical sliding-block breech and it fired fixed QF ammunition of a number of different styles. The guns were mounted in Grusonwerke gun turrets or in armored casemates on central pivot mounts and used in an anti-personnel role.[1]
Infantry gun
In addition to its fortress gun role, it was deployed in an infantry gun role. The guns were mounted on light two-wheeled box trail carriages without a recoil mechanism and protected by a three-sided gun shield. During 1914 the Germans captured large numbers of these guns and used them in the infantry gun role mainly to engage enemy machine gun nests in support of infantry assaults. In 1916 the Germans had 450 of these infantry guns in service.[1]
Also, I found the original manual the names Gr. (P.) Gr.m.P. (P.).
It’s not a P. in parentheses, it’s a ? and the . after the P is actually the dot on the question mark. This makes sense because it’s a British document from 1918 and, judging by the abbreviation table in this document, Gr. would just be Gross which just means “Large” and Gr.m.P. would be Gross mit Phosphor which means “Large with Phosphorus,” neither of which make sense. So now I am trying to find the actual designation, but I don’t know where to start.
I know of that, its Notes on German Shells 1918 Second edition. (Or first)
And your assumtions is completly wrong.
Gr. Is Granate (Grenade) and m.P. is mit Panzerkopf (with AP head.)
This is not my assumption, this is this own document’s abbreviation table.
The document lists Granate as G., not Gr., and P. is listed as Phosphor. Even if this was P. (P.), that would be Pulver.
Granate mit Panzerkopf would make sense, but this document lists the abbreviations as Gross and Phosphor.
Probably some translation error.
m. P. = mit Panzerkopf
If Gr. meant large it should be in lower case letters
→ gr. for gross
Oh wait true you do make a good point.
That also lists m.P. as mit Panzerkopf, your 3rd picture
11th line.
I have added the 15 cm Mi.Gr.44 SAPHEDS-FS 70 kg 344m/s however unknown filler mass and type (tho most likely Amatol, because good, save, cheap and castable, like in the 15 cm I.Gr.)
If anyone knows the Filler mass that would be nice.

Big news, with the upcoming 2 part vehicles such as this
EldE 98: Missile Trolley we can suggest a pulling vehicle and a gun on a standart lafett, if it can be used in the pulling configuration. Such would be an example Sd.Kfz.7 with 8,8 cm Flak or so.
So feel free to post here pictures of big aa and other guns in turrerts that are on a trailer or with trailer and pulled, that can be interesting and suggested after the update is live.
Like this.

I see the label on the bottom right, was this meant for the Porsche Tiger?
To my knowlege the Vk 30.01 (p)
“Work on the Typ 100 renewed in February of 1941, but the tank changed radically. The new gun required a new turret, one with an impressive turret ring diameter for the time: 1900 mm. There were even more ambitious plans of installing a 105 mm L/52 gun, like on the Pz.Sfl.IVa. Taking the drafts made by Krupp, Porsche K.G. prepared a reworked variant of the Typ 100 by March 5th. The hull of the tank became much shorter (6.3 meters), but widened around the turret ring to fit the necessary diameter.”
