Sort of a combination of hobby and machinist ?........Im probably not permitted to mention the competition,but there is a long running series on a slightly earlier version of yours ,an AL300........incidentally,a somewhat similar machine is still sold ,so you can probably get a start by downloading a parts list at least from Hare and Forbes/HAFCO/Machinery House.....they have free downloads for all their machines.........they are still pretty similar....V belt head ,with Norton threading box......although there will be differences between manufactures.......In Taiwan there are/were whole districts of factories making the same or very similar machines ,in the millions.Many have gone from the scene,a few have gone into CNC,and some are just fronts for Chinese stuff.
