There were a fair few which were picked up as private souvenirs - and mostly subsequently binned. A few came back as official war trophies, some for training use - we had one or 2 in NITAT. All were in a really manky condition; the conscripts just did not look after them. Most were destroyed or dumped at sea.
One thing that those who could did was to get hold of 30 round LMG mags which fitted the SLR and gave an extra 10 rounds.
