Unknown polish WW2 binoculars, serial number 83448

[grooveshark]

Hello.
I got the one WW2 polish binoculars, but it doesn`t looks like other Polish binoculars from this period. The stamp of manufacturer is missed, and serial number is 83448. I made some research, and find out, according to this book, http://binoculars-cinecollectors.com/History_of_H.pdf that the last known Polish binoculars had a serial number 82754. Also, the case for binoculars looks like early model of Soviet RKKA case.
I suppose, this binoculars were made in evacuation in Lvov.
If someone can give more information, please, explain.
Thanks.
