M 170 and M 270

[dirk Peeters]

We have made an investigation
First we have this document

here we see clearly indicated that the openings for munition has to made in the M 270 not straight
as with the M 170

an M 170 has two versions
an old one and a new one
The old one has the openings horizontal
thats like this

and the M 270

Why do we say the vertical openings are the modern ones
Well each M 270 has vertical openings
and as we know the M 270 is the newer version of the M 170 we can say
the M 170 with horizontal openings are the first M 170
and the second version of the M 170 has vertical openings

so we see clearly the M 270 have all vertical openings for the munition
Who has info of danemark , Holland and Norway ?
can we say this goes for all the Atlantikwall or only for France
your opinions please

Also as we look in the books of Rudy Rolf (typologie we can see the same
straight openings for M 170 and not straight for the M 270 ....

It looks more safe. From big wide openings, to narrow openings, to narrow openings placed in an angle so no direct hit possible into the ammunition room.

[dirk Peeters]

I have the same thoughts Arthur
I know you visited a lot in the atlantikwall
do you have found a M 270 with horizontal openings ?

[dirk Peeters]

here two special M 270 which have cellars in the munitionrooms
one is also constructed in " mirrorversion"

here we give the normal cellar that is the same in each version and always in the gun room

Hanstholm I, M 170? don't have more inside pictures, but it looks like two different openings.
