If you like to make things, like some eccentrics like me, I have built perfect working copies of the Bygrave (the best for LOPs) and Fuller (best for everything else, including lunars) for virtually zero cost. If you want build details, please send private email request. They really are very easy and cheap to build. No other slide rules come anywhere near for accuracy.
