Man when I was younger and moved around the country allot.I met guys that would make a living by driving around the alleys of the rich neighborhoods in the cities and pick up the stuff they would find that was being thrown out and then take it to auctions and or Flea markets and sell the stuff.Laurence is correct in saying that these people throw out better stuff than allot of us makers can afford
You know the old saying..One mans junk is another mans Treasure..
I have also seen this around storage buildings where people either quit paying for the space and the owners just throw there stuff away or people clean out the storage and throw allot of old stuff away as they don't need or want it anymore.Whatch around old estate sales,when the selling is done allot of the time the heirs will just throw away the stuff left over as they don't want it and need to get rid of it.The fun one is when a older gentleman passes away and his wife doesn't understand about the old tool shed,other than it is a bunch of junk to her,will just throw his old junk away

And if you can get ahold of it there is usually a treasure trove of really cool old stuff,I have gotten allot of Black Smithing tools from clean ups like this that would come into the scrap yard,along with old Knives

that needed a clean up and a good home...
In the spring time is a great time to start checking around old scrap yards,Those old post vices pop up regularly,and other cool things..
Great find Laurence,Remember if you want to get rid of it just send it to me
