I have an old Queen vibrating shuttle machine, restored and working. I think (not sure) that this is the same machine as the Minnesota. The manual for the Queen is available (Tias, I think). Might be worth looking over. There is a similar model, "Home Queen" or something, which is not the same machine as the one-word Queen. The Queen takes a slightly longer needle than your usual needle, though you can in a pinch just set a regular need down 3/16" or so, as I recall. Otherwise the lower thread will not pick up. It's a nice running machine with a beautiful sound. I can be more precise about all this (I have notes and can look at the machine, which I have not yet sold (I am not in business, but they do tend to proliferate if you don't sell or gift one from time to time!), if that might be helpful.
