If you've tried to contact them to no avail, then I think you've done your duty. If you are copying these for the cost of materials and time and not for"profit" then I doubt there will be an issue. I've been trying for 10 years to get material like this from over there from folks like Klaus Morhammer. The material is just not available. Please help those of us out that are dedicated to this style of tuning and let us have this bit of our history as a point of reference.
