Try metalclays4you. Half round isn't listed on their website but it is in their eBay listing. Several sizes available. No connection,I have to solder the sides and the rear to these tenders, I wish I had some half round wire I put it on the inside instead. If anybody knows any firm that I get half round wire let me know please.

I've seen 18 gauge half round, but I don't know which is near .4mm? Any idea?

Hi Sean. The fireman tools tunnel comes as a white metal casting (which is good for me).
