Ah, that's Wood's Metal, which has a lot of bismuth in it. Also sold as "Cerrobend", I think, for filling small-bore pipes so you can bend them, then melt it out. Good for soldering bits of white metal - if everything can be held together, you can do it "boil in the bag", but things need to be really clean and acid flux is best, because greasy plumber's flux doesn't really liquify enough at 70C.

Was that Midway as in Midway the firearms and gunsmithing suppliers? If you try to order from one of their websites that isn't in your country they won't ship to you. They do have a German branch
http://www.midwaydeutschland.com/
They are often quite helpful there for stuff that isn't listed on their site but is on one of the other Midway sites.

allanchrister:
Yes, its the Midway gun people.

Kevin in Midway UK was quite helpful and they do have TIX, but won't ship to Germany as it conflicts with their other offices.  The German branch of Midway are most unhelpful, as I said before.  If you don't have fluent German (and I don't for a long protracted order for silver bearing solder and quantities of TIX...even if they knew what that was) they just put the phone down on you.  My fault I guess for living temporarily in Germany.

I did have a successful discussion with another vendor - cupalloys, who have a similar material called LT145.  Low temp solder for brass which melts at - 145C - called them, discussed the need, filled in an internet order, and they confirmed that its on the way.

Cleaned up my dial rings ready for a second soldering attempt.  Someone mentioned about the dial numerals being 'serif' or 'san-serif' but thats not an issue - i'm using Roman numerals - much classier.
