Found the quote below on a bomber command website that also talks about the Dutch resistance, there is a museum wedsite as well but no detail to speak of. The page this came from also shows a former resistiance member standing beside an M1 Carbine that was dropped by the Allies.. he never turned it in at the end of the war.
In early 1943 the family awoke to find a horse and wagon in front of their house. No people were to be seen. The wagon was loaded with rifles, bren guns, bazookas, and ammunition -enough armament to supply 25 men. The guns and ammunition had been dropped by Bomber Command and brought to the hideout by other members of the Resistance unknown to the Groenvelds. The weapons were stored in the hideout and used regularly by Resistance members in the area until the end of the war.
Apparently Allies did not start dropping weapons in Holland in any significant amount until 1943..
The quote below is from a research paper from the University of Tenn.
In August 1944, the SOE was able to drop 30,000 hand weapons into
Holland, where most were quickly hidden by members of the Dutch Resistance. The
Nazis were able to detect 15,000 of the weapons, but the remaining arms helped the
Dutch Forces of the Interior provide substantial help to the liberating armies in the
eastern and northern parts of the country.
