It was well known that captured British and french Munitions were used by the Germans ! examples of this can be seen on Guernsey minefields they were called Booty.
What wasnt generally known was that the russians used captured German bombs , although the Russian fuzes wouldnt fit they were simply Staked in using pieces of wood as wedges.
Above are my interpretation of a staked in fuze.
