I'm not a UK Theodolite expert. But this is a very nice looking theodolite, and I love the look of the extra long telescope. From what I can tell, English theodolites have become very affordable over the last decade or two. As a result, you can get a good deal of eye-pop with a theodolite for a pretty good price.

I guessed at the circa 1860s date. I didn't see much info on Thomas Street on the internet. He apparently had a long run, and then went into business with a relative (probably his son) i the mid 1860s.

Here are the key specs relating to this instrument.

14.5 inch telescope as shown in picture

2 inch needle

5 inch horizontal limb

Very nice and clear optics

No stadia wires or crosshairs visible

About 11 inches tall

There is no box for this theodolite

The instrument cannot stand upright by itself - see the pic of the underside of the Theodolite. The winged nut at the bottom of the theodolite extends beyond the Theodolite base. I will include the wood base shown in the pics, so that you can display the instrument.

Everything I have is reflected in the pics, and the instrument seems pretty complete.
