Thames Valley Police is running a four-week firearms amnesty for certain Bruni blank-firing pistols, now illegal to own.
The amnesty runs from February 2 to 27, allowing people to hand in the weapons without prosecution.
After that date, possession could carry up to ten years in prison.
Items can be surrendered at Aylesbury Police Station, with police urging anyone unsure to call 101 for advice.
