Brilliant work and for a good cause too..
Give me a shout if you decided to use anyone else as I have a friend in the watch game over this neck of the woods who has had a few bad experience with one of the restorers but I can't remember who he said.I use a company in Chelmsford to do any dial refinishing for me, I've heard of Soni in Wembley but I've never had occasion to use him yet. I have a huge selection of blued seconds hands now in 4 different pinion sizes, I bought a shed load from an American chap who has mountains of veteran parts!
The way to blue steel is to highly polish it then heat it so it changes colour then when it's at the colour (or near to) that you want you stuff it into water and voila. I make and blue all my clock hands on site. Never done watch hands but I'd guess instead of 30 minutes at gas mk7 your talking more like a couple of minutes. There are also chemicals to blue steel but those suck in my humble. You can't beat heat treated hands for absolute beauty.Lovely story and amazing transformation. On a side note I've often longed for a blued second hand for one of my stainless steel 7005-2000s. Anyone know if this is easily achieved?
Here is some hands I blued for one of my clocks.
