I used exactly Jeffs approach and came up trumps, had to wait a while but when they changed their display got a bag of blocks, brochures a few cushions etc.

Hence I have a couple to spare, if you are local in the UK you can have them for nothing.

They do look good so drop me a line when you get a chance, or do you want to swap for that Siffert, I hear they are not so desirable these days and everyone is actually wanting display blocks.
