Don't know if this helps but I went to a materials supplier geared up to supply lots of different stuff in small quantities to lots and various materials and sizes and shapes etc, based in Stoke-On-Trent they're called Noggin End Metals.
As I say I went there today and only spent a few quid but the chap there (I think it was Mike?), asked his good lady to make us both a brew, very friendly and helpful, here is a link **LINK**
