The sources below don't fit into the menu categories, so here's a nice place for them to live.
Although not a primary source, I also found a wealth of information about the Inverto tools in eBay auction listings from seller burty0_0.
burty0_0 are one of the top watchmaker's tool suppliers on eBay. They supply high quality tools in excellent condition. If you want to simply buy a watchmaker's tool and get on with using it without having to spend a lot of time rehabbing it, burty0_0 is the place to go. Of course, they are experts in the value of good quality watchmaker's tools and when buying from them you should expect to pay prices that reflect their expertise. burty0_0's listings are crammed full of information and pictures about the tools they sell. Even if you never end up doing business with them, it is worth paying attention to their listings purely for their educational value. |
