German H-block?

[21stud]

Hello all barners, I am flathead enthusiast from Finland. Been lurking here long time and learned a lot. Thanks to all members here, sure a lot of knowlegde!

I thought I show some photos of this block I have . I only have block with flywheel, crank, rods, pistons and cam. No oilpan, heads, timing cover or int/ ex manifolds for this.

My past experience is -37 21 stud engines, so just recently I started to identify this one.

It is 24 stud, 239, appears to be STD bore. prewar I believe, because short snout crank with small bearing journals. Bellhousing have cast H and VR below it. No bulges on oil pan rails.

Cam gear is aluminium, surprise? I think it usually is fiber in prewar engines?

I believe it is german because there is mahle pistons and based info I found from this swedish website:

too bad, no photos of similar engine but later ones are covered well.
mine do not have rear distributor boss in bellhousing, so I think this must be early 24 stud Germany engine. Similar with USA blocks.

Very strange is the fact it's 3-3/16" bore? and cylinder walls are thick. I allways thought all prewar Fords were 221"? is this German equivalent Mercury block?

Other real suprise was main bearings. I assumed this must have small mains as crank is short snout type. but what surprise was to find 81A markings in those bearing caps? still crank have 2.4 mains but bearing shells are very thick to compensate difference? I have never seen bearings like this?

Do you guys have some info about these, anybody else got similar engine?

take a look attached photos, please.
