 It's in the Fisher catalogue as Parlodion strips: (C$651 for 100 gm).
 It's also in the Electron Microscopy Sciences catalogue: C$82 for 10 gm,
 also as Parlodion. The VWR catalogue has Necoloidin (which is/was
 the low viscosity nitrocellulose sold by BDH), but only as a solution.
 Catalogues don't seem to index anything under pyroxylin, cellulose
 nitrate, nitrocellulose or even celloidin these days. The stuff in my 
 lab is all from the 1970s and early 1980s when it was much less
 expensive. Fortunately you can go on using it over and over again.
