I have just acquired this item and am wondering if anyone could identify it? The only marking shows that it was made in England but nothing else. It is made to sit on a flat surface as shown while the thumb screw at the right hand end allows levelling via the bubble level alongside it. The large tubular screw? at the left allows the rise and fall of the scope by about +/- 5 degrees. The calibration marks go to +/- 140 in unit increments. There are no crosshairs or other target in the scope but the image is inverted and has quite a bit of magnification. There is also a pair of open sights on the top for initial sighting.
Any ideas?
Ian.

Could it be some piece of antique surveying equipment? It doesn't look too unsimilar to this: https://www.ebay.com/itm/J-C-Ulmer-18-D-Surveryors-Surveying-vintage-antique-old-brass-Level/271117564925?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D1%26asc%3D20160908110712%26meid%3Df0a23c8357c2410ebe4697595777888c%26pid%3D100677%26rk%3D1%26rkt%3D10%26sd%3D271117562709&_trksid=p2385738.c100677.m4598 (https://www.ebay.com/itm/J-C-Ulmer-18-D-Surveryors-Surveying-vintage-antique-old-brass-Level/271117564925?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D1%26asc%3D20160908110712%26meid%3Df0a23c8357c2410ebe4697595777888c%26pid%3D100677%26rk%3D1%26rkt%3D10%26sd%3D271117562709&_trksid=p2385738.c100677.m4598)
Just what popped into my head when I saw it.

Kim,
I thought the same originally, but it has no provision for traverse, ie a turntable or similar. It is only designed to move up and down.
Thanks,
Ian.

It looks like a builders Dumpy level used for setting out on building sites.

There was an instrument used on a "table" to make a 'sort of' map, I can't remember the name, that looked like that. I never saw one but heard about them and the description matches. I thought they would have had some sort of cross-hair in it though. It was used by sighting on the distant object and drawing a line on the table along the side of the base of the instrument. Using various distant objects at different angles ...... Etc :-) I think I came across this thing/description when I was into "caving" back in about 1957 or 8 so it's no wonder I can't remember the name. :-)

I think I know the sort of device you are describing, Lew. Not in this case however as the base is decidedly triangular in shape so the sides are not parallel with the scope. I will revise my comment about no crosshair. I have just removed the eyepiece end of the scope and there is a carrier with only vertical adjustment for a horizontal target hair but no actual hair.
I am still intrigued by the large calibrated adjuster.

Some kind of inclinomiter for setting out shallow falls maybe for road, rail or drainage use?

Could it be military. Ian S C

I'd go with this :-) Drainage falls are usually 1:40 to 1:110 so fitting in with the calibration numbers on the dial.

Its an artillery scope ;)

It'd have a wider range of angle at least 0-45 degrees
