Hi dc key, and let me copy into this post an extract from VHUB's most recent 10K which mentions having a California manufacturer (specific name not mentioned). This doesn't fully answer your question by any means, but it does mention that they do use some California-based manufacturer which might or might not be PLY. Here's the excerpt from the 10K:
We use third party contract manufacturers to produce and finish our mods (“Mods”), including our Limitless Mechanical Mod, from facilities located in both Southern California and China. Our Mods, which are made from a metallic material such as steel, brass or copper, are custom machined to meet our design specifications. Once machined, unfinished products are delivered to our location in Simi Valley or to a third party service provider to be buffed, polished and to add various treatments and embellishments, such as paint and engravings. Finished products are then held in inventory for distribution and sale. In our fiscal year ended June 30, 2015, we relied on one manufacturer to machine all of our Mods and in the fiscal year ended June 30, 2016, we relied on two. Although we have relied on a limited number of manufacturers to machine our Mods, we believe manufacturing capacity is available to meet our current and planned needs. We do not currently have any long term agreements in place for the manufacture of our Mods.
Hope this helps and sorry I could not be more definitive.
