Definitely sounds like cast iron which can have a density of 7,100kg/m3, steel is denser so more like 7,400kg/m3 upto 8,000kg/m3 for SS. |

AdeV, What did it turn out to be made opf ? Dave |
| AdeV:
I never did find out I'm afraid; it transpired the chap only wanted the brass outer piece making, he'd already got the internal gubbins. I'm pretty sure it was either cast iron, or steel, based on the colour & feel, but once I found out I only needed to make the brass outer, I didn't think much more about it. |
