David thanks for posting your interesting story, I type this as I pick myself up from the floor where I fell after reading about your 50 lathes, WOW
Have you posted a group shot of your babies? I would love to see them all lined up 😮
I have two which I cleaned up and serviced and I’ve been thinking about having a couple of nice oak boxes made for them by a carpenter friend, after i finish collecting a few more attachments, it never ends 
I was thing about getting a unimat at one time but I was put off by comment that they were too large for watch work, regardless I like the look of them and attachments seem readily available..
