I have received a reply. Small business that tends to answer emails every few weeks in one sitting......I received a reply to every request for information separately, all within the same day. Unfortunately they do not ship to Canada at this time. I have one set I received when I bought a scope off the EE and they are very good caps.....best in the bizz in my opinion. For those that have lost the eyepiece I recommend a small amount i.e. a thin layer of silicon applied to the inside of cap. Adds just enough tension to keep the cap on for those slight variations in manufacturing tolerances.
