Just thought I would share this story. I was in the 4th grade and the year was 1958. We used to go out for lunch and then walk on a bike path behind the school (PS 188 in Queens NY). I noticed a piece of metal covered with some leaves and when I kicked the leaves away there was a gun, which years latter I recognized as a Grease gun. I played with it and even pulled the trigger (had no mag in it) and then left it and told the school principle I found a gun. I went back to class and 10 minutes latter 2 officers came into the classroom and asked me to show it to them. I remember I asked them if they could put the siren on and they did. Showed them the gun, they looked around and found nothing else. I remember thinking it had a lot of gadgets attached to it like the ejection cover and some other 2nd trigger(?) thing plus its wire stock. Didn't really look like a real gun to me at the time. It was about this time that there was some mobster who was machine gunned in an Italian restaurant on Queens Blvd. and I wondered if this gun was used there.
