I have been trying to buy some thin lead solder for the wife's hobby stained glass work. she has some 3mm diameter solder no problem but needs some smaller solder for fine jobs. It has to be non-cored i.e. not resin fluxed as she uses a different liquid flux and a lead type low melting point. I found a manufacturer no problem and after satisfying that she wasn't using it to solder potable water pipes etc. there seemed no problem. when I placed the order the company wanted my VAT no and as I don't have one she wouldn't sell it to me. A couple of days ago there was a question about soldering and the bead that you get and Jason said to the person have a look at Cup alloys and right at the top of the page suggested there was the perfect solder for my wife. I never thought of going to them for lead solder and after a quick call dropped in and collected some LT145 Soft Solder 1 metre 1.2mm dia . as I only live a few miles away from them. problem solved.
