Hi Big Dave,
really nice collection.
Your Ice-Mine is 100% sure the German-made Model M42, clearly to see on the shape of
the shoulders of the bottle and the Long bottle-neck which has towards ist openinig a Kind
of wider seem to prevent the fixing-rope from sliding-over. German-Pattern that I have seen
do not cary any markings in the glass - if You check for further threads here You´ll find one
were it´s mentioned that there´s one specimen with a No.8 on the bottom - I would be glad to
see a photo of this mark. What I did realize is that there some made from colourless glass and
others from clear glass with a green-blue-shade, here soom pics:



Here something on the FINNISH Pattern:
Finnish-made Mines are existing without any markings but also with a mark (mould into the glass)
which is consisting of the letters SA in a square and below the letter P.

More interesting than the markings on the Finnish Mines is that there are
at least 2 different size of the bottles existing, see next photo that the seller
of my specimen did provide to me (I was to late to get the second size bottle,
which seems to be quite rare, I am still having nearly tears in my eyes),
Sorry, got only the photo - without dimensions:

I think this does also answeranother thread here on the platform.
Here some photos of the Finnish Ice-Mine in the original Transport boxes,
check the stamp-marks:





Third Photo from right shows a box in which You see in the right Corner a Starter-Mine with hole in the Cap.
Second type of packing are these thick-walled cardboard tubes (first photo from right).
I also think that material had been going from Finnland to Germany or the other way so that without any
doubt also German remains had been after war in the Finnish stocks - but the Patterns and fabrication are
according my believe to be split to German and FINNSH Manufacture / Pattern (design).
Cheers,
Ralf
