Hey George, I'd be willing to bet that if you put the time into the expedition you will come home with some 'goodies' from the property.
I have had some notable successes over the years using my detective skills and investing the time to really ferret out the large and small leftovers on farm dumps, creeks and river beds.
Actually the greatest challenge is to tactfully gain the owner's consent to wander over his home paddocks.
Two weeks ago I visited, with full consent of course, a local farm where a Grant had been scrapped out. Several Notable collectors had been over the place repeatedly yet I was till able to collect a quantity of very rare internal fittings and bracketry which went direct to a grateful local Army Museum to complete their vehicle!
Always worth the effort and to my mind one of the most satisfying aspects of this hobby
Cheers
Phill
