Ahhh, the impossible to find spool. Those things are hard to find in decent shape. I had an extra from the parts-machines I bought, but I managed to mangle one cleaning it. Jim told me they were fragile....I had no idea just how fragile. I've thought several times about trying to have them re-created out of aluminum. I'm betting they could be turned pretty quickly.....the tricky part is getting the bore for the main shaft to be exactly straight.
Last week I saw an ad on Craigslist out in CA for a Jewel Box and Deluxe upper that a guy sold as a pair for 1000. They looked intact, just minus the front door and a few minor odds and ends. I contacted him, but missed the sale by one day. I hope whomever bought them, brings them back to life.
I am just finishing the Jewel Box Upper...see attached pic. I am waiting on the mirror for the background, and I will have the base ready for trim this weekend. Sorry I couldn't help you.
