Thanks for the welcome guys,
To answer a few questions.
Regarding the optics - The primary mirror is 210 mm ( a bit over 2 1/4 inch ), coating almost completely gone. secondary mirror and holder are AWOL.
Finder scope is a unitron 10 x 40 - maybe salvageable but crosshairs gone, eyepieces - bin job.
It had a brief career as a periscope during flooding, twice.
It was bought to watch Hailey's comet by a private school I'm told it, then not used again then pulled out during renovations about eight years ago and destined for the scrape yard which is when I acquired it.
It weighs in at around 400 kilos or 900 pounds if you roll that way.
The research I have done so far tells me it is at least 75 years old and possibly over 100.
I posted it to Reddit a couple of days ago and they suggest posting it here, there is quite a bit of interest in seeing the renovation so I am thinking of videoing it so people can watch the progress.
