Here is the truss rod cover screw- it is less than 3/16” in diameter, so a small Reed Prince screw driver is in order. As you can see, the cruciform slots are buggered. My hope is to find a nice set of screws and the proper tool for them. These are from 1927 and were used with straight head screws if the factory supply had run out. The neck is a plectrum conversion to a Bluegrass banjo with five strings, and also dates to 1927. Maple from a 1927 tenor neck was used to widen it. All inlays were salvaged from the necks, and the fret board is made of Brazilian rosewood from an 1890 piano plank. Here is the back of the resonator. I purchased the banjo in 2017, so it has taken almost ten years to bring it to this state.
