Thanks Whig!   an interesting read for such a seemingly insignificant item.  Maybe OK for ice and snow, not so much for jungle ops...canvass, unless properly, and often, treated goes south fast.  I'm also surprised at the shoddy workmanship (seams) on this, coming from RIA.  Wondering  if 32K made, how many in even decent condition exist?...and on the market.  I haven't been able to find one, except a repro..Thanks again for your trouble, sir!
