I cannot help with purchasing and shipping to the UK, but I can report on the instruments themselves as I received in 2010. The chest piece and bell is high quality, nicely finished, and same dimensions and contour as the 1940's versions. The tubing is a little light weight but the not a cheap stiff plastic sometimes seen. The head piece is OK and is adjustable, although the spring is a somewhat lightly built. The ear tips are not right all and must be replaced with black pastic. These are easy to find at any medical supply firm. Actually a great buy, if only for the chest piece and bell.
I ended up discarding the head set and ear tips, and used a 1950's original of higher quality.
Here is the US my order came very quickly, but of course that was in 2010.
Hope this helps.
