Yes, of course, I will share any info that I have. My machine is probably earlier than yours, it is 1943, had the "war finish" and came off of a ship that was scrapped near here, so it had very little wear on it. It is equipped with a taper attachment in good working order, and has a threaded spindle nose; in my shop that I sold, I also had another Regal the same size, but with about 8 ft C-C, it did have the type L spindle nose. The one that I have now, at home also came with collets, but I had to make the draw tube. When I made the metric transposing setup, it would not fit in the gear guard, so I made a new on fabricated from steel sheet with a hinged door, making it much easier to change gears when necessary for special or metric threads. Another thing I did was to exchange a two speed motor for the one that I put on it when I bought it it (It originally would have come with a DC motor for shipboard use, but it had been removed by the machinery dealer before I bought it. The two speed motor allows me to have a top speed twice as fast as original. I found that prolonged operation at that high speed is bad on spindle bearings, as there is no provision for automatic oiling from the headstock, hence the Gits oilers at both ends of the spindle housing; this was an expensive lesson!
