MtMan-List: Re: Mt man-List: rubber ponchos

My thanks to John, Phyllis, Don and Jim for the interesting treatise on
"vulcanization" of cotton cloth with natural rubber.
Would it be fair to  assume that if one were to show up at some doing
with a cotton/canvas cloth which had been "rubberized" he would be period
correct?  To elaborate, if one were to take pillow ticking or #12 canvas
and treat/coat it with a "natural rubber" product (ie. say dried Contact
Cement or a clear type rubber product used to coat some tools)
would/could he be shot on sight?  Of course the main question is, how
common were such items in the Rocky Mountains during the Fur Trade 
period and is it fair to also assume that the typical trapper had such an
item. Or, were such items used for the packing of goods west for trade by
pack trains?  The more I think about it I tend such items were rather
scarce.

Any further thoughts????????
