I've been looking for sites to see if any would document where various products come from [to see if I had to start my own or not!], and I found
ProductFrom.com - Where have things been made? - ProductFrom.com
and they have sections for everything - even trumpets, cornets, and flugelhorns!

New Product Form - ProductFrom.com - you can submit products here if you so choose. Useful tool!

A Getzen fan or the company itself already included themselves in this site: http://www.productfrom.com/company/332/
