Hi Jose and Ken,
Looking at the issue I was seeing coming about managing the orders, payments and delivery I would like to know if Jose can share with me (us) the drawing and details about the silicone quality (and hardness) used for the working BT seals. Then I'll try to find here in France a manufacturer and make the seals available at least for European owners.
Of course, it can be perfectly understandable that it's not possible if there's any intellectual property rights attached to the design.
