My Collection of Victorian machines is the worst in this regard because most were made before the SAE and Metric standards were set, so they can be whatever the factory decided to make for that part... I have had to take careful measurements and manually reproduce three different screws so far..
My father was a mechanic for many, many years and I learned that from him. I wasn't sure if there was a special screw that I needed. I lost the screw on my Janome that held the foot on. I absolutely detested the dealer that I bought my machine from and spent an entire Saturday morning driving around to lots of hardware stores, box stores and vac & sewing shops trying to keep from having to go to the dealer. In the end, I did have to go to the dealer and they sold me a used one for $0.99. Anastasia is helping me out!!!
