[alocky (Andrew lockwood)]

I've acquired a fairly interesting telescope, a 7" f10 newtonian, which dates from the era of silvered mirrors. There's no doubt some of the components came from a professional instrument maker of the day, but the mirror cell and mirror suggest that a replacement mirror with a different focal length was added at some point. I'm not even convinced the spider belongs in this tube either, as it all looks a bit of a mix, but the fabrication of the brass tube is quite impressive.
Anyway - I've attached some pictures and would be interested if anyone can positively identify any of the components. The finderscope looks similar to ones found on Calvers and Brownings of the era, and the focuser looks like the one on our Calver at Perth Observatory, but the mount is completely different to anything I've turned up in searches.
