I will have a number of rubber and plaster production molds available for sale, large molds will cost $500 each, for the most part they cost me around $300 in materials and more than half a day time to make. These are the molds used to make many duplicate casts in cast stone or concrete.
Preferably a similar sculpture outfit can make use of these so I can get them out of my basement.
Most of the larger molds weigh in the neighborhood of 100 pounds.
I will generate a list and maybe photos soon. These are not likely going to be shipped as they would have to be crated and packed and I no longer have access to freight truck dock shipping.
They are located in NW Iowa
