German artillery in Finnish Civil War 1918

[Landsturm]

I’m researching the German Ostsee Division and Landungabteilung Brandenstein that were sent to Finland in spring 1918.
What I’m trying to find out, is what type of artillery these formations had.

The artillery units were:
Feldartillerie-Regiment „von Holtzendorff“ (1. Rheinisches) Nr. 8
- 6. Batterie
- 7. Batterie
Bayerische Gebirgsartillerie-Abteilung 2
- 7. Batterie
- 8. Batterie
12. Batterie
1. Batterie/Reserve-Fußartillerie-Regiment Nr. 14
4. Batterie/2. Garde-Reserve-Fußartillerie-Regiment
Marine-Bootskanonen-Abteilung

Suomen Sotilas (3/2008) magazine mentions:
75mm ”mountain guns”, 150mm ”howitzers”, 105mm ”cannons” but doesn’t include models or anything else.
I’ve tried to find photos, archives and books, but there seems to be very limited amount of information about this. Maybe someone can help out?

Attached is the only related photo I've been able to find online (Germans in Malmi, Helsinki)

Funny, I spent several days on this and now that I return to this subject I immediately find a mention from archived Sotahistoriallinen aikakauskirja 29/2010 mentioning:

"... Kenraalimajuri Wolfin osaston taisteluvahvuus oli noin 3000 miestä, 13 kenttätykkiä (10x75 VK/L14, 3x 150 H/02), kuusi miinanheitintä ja 80-90 koneki­vääriä."

"... Major General Wolf's detachment mustered approx. 3000 men, 13 field artillery pieces (10 x 75 mountain gun L14, 3 x 150 howitzer 02) six minenwerfers and 80-90 machine guns."

So, it appears that at least 75 mm Gebirgskanone L14 model 1913 and 15 cm sFH 02 were there. But still eager to learn more..

Found it on my own... Suomen kenttätykistön historia I :

Baltic Division:
2 Bav. Gebirgs: 12/75mm mountain gun L 14,
1 Bat Heavy Res Art: 3/150mm howitzer 02,
4 Bat Guards Heavy Res Art: 3/105mm cannon 14

Detachment Brandenstein:
8. Field Artllery Reg: 7. Bat 4/75mm cannon 17 and 8. Bat 4/105mm howitzer 16

Re-equipping:
"The Bavarians received eight 75mm Skoda mountain gun 15's and four 105mm field howitzer 12's."
