[pic removed]
crappy photographer (me) but if it's visible:
-identical labels
-varying locations of manufacturing
-and apparently, Standard and BWD share a warehouse/office on Long Island
with manufacturers buying and re-buying merchandise these days, it's hard to guess what's actually in ANY box you buy, but the general understanding that not every distributor makes every part they sell and that a lot of "back channel" buying goes on between them should be reasonable.
P.S. both of these items pictured were from the "cheaper" line of BWD, so North American quality cannot be ruled out based on which line either.
P.P.S. no, I don't have anything to gain by recommending BWD, I just found it odd that they (as well as G.P. Sorensen) were sharing office space
