A nice set of binoculars and loaded with mystery too!
I have not studied WW2 French or Italian binoculars. However for the completeness of our discussions on this thread I have a few observations :
1) what seems particularly distinctive about your binoculars is that they are made from light alloys like the German Dienstglas from say 1939-45. No flashy brass is evident! The binoculars appear well made structurally and they do appear to be of 1940's vintage.
2) The placement of the single screw securing of the prism covers is very distinctive. And the placement of this screw is in a different position to other Eastern European WW2 binoculars which favoured a single securing screw on the top prism covers - eg :
(i) Russian WW2 standard binoculars 6x30
(ii) H .Kolberg ,Warszawa and PZO,Warszawa (both 6x30)
(iii) Czech Army variants:
Optikotechna,Prerau vz9/13 6x30
dow Dienstglas 6x30 ( a derivative of vz9/13)
postwar Meopta vz.48 6x30 (a derivative of vz9/13)
K.P Goerz,Bratislava vz9/13 6x30
The above examples are all 6x30's , but as a rule 6x30 and 8x30 binoculars share the same body and external dimensions.
The Japanese binoculars which appear in Dr Rohan 's Guide to Hand held Binoculars
do not match your example.
The provenance supplied with your binoculars states that they were a 2NZEF Kiwi soldier's trophy ( so liberated in Nth Africa or Italy during WW), so it seems to me that it could be an Italian set . The problem is that not many optical collectors are into Italian optics and thus very little info on these is shared. And the Italian WW2 binoculars that I have seen have an Italian makers commercial logo on the top prism covers. etc
Sorry Mark , this rambling note takes us not much further .
