Hi, Out of the over 200 different Michigan hutches I've dug a few myself, most of them from Privies. not many from dumps. But I've dug the same common ones over & over again. The most common from Detroit has got to be the Aqua G. or Geo Norris, Then Wegener but Earl McBride & Pollard 3rd but close to the Wegener. both about the same. I once dug like 8 Cobalt Blue G. Norris Hutches at the bottom of one Privy Hole. Pic below. LEON.Extraordinary bottle collection sir! What percentage would you estimate you have dug yourself? Mostly from dumps or privies?
