I mentioned the possibility of turning it into transposing. That is a pretty big task, but a more doable one is simply to remove the top key treble end, cut 1/2² off the keyframe that end, slide it over and fix it in place (making sure the backs of keys line up under jacks), and make a larger cheek block for the bass. You¹ve lost a note, but it plays 440. This is more or less assuming it is designed for 415, which seems quite possible. My memory is a bit vague, but it seems to me that that was an advertised feature of authenticity at a certain point (along with the becket-less pins, the screw-less jacks, and the registers you change by reaching around the side of the instrument). Those supposedly tapered tuning pins are a real pain. They aren¹t actually tapered except for a short segment at the very bottom, so they don¹t really get much tighter with pounding in a bit, as a truly tapered pin in a taper drilled hole would. I bought a similar kit Z instrument (from someone who never quite completed it) to use as a rental, and got frustrated pretty quickly with those pins. I drilled out the holes in the block and replaced with zither pins. End of chronic slipping pins problem. Also, beckets actually do come in handy <G>.
