Clean the exposed optics only with high-absorbent cotton or lens-cleaning paper; never use handkerchiefs or clothes . Can’t copy the link right now

For surveyors who preferred simplicity and lower cost, Hilger & Watts offered vernier theodolites. Their brochure (shelfmark Hil.479) explains reading to 20 seconds of arc, details tripod options, circle figuring, and provides full specifications for telescope, circles, vernier scales, spirit levels, and levelling base.

Locate the brass positioning pins in the baseboard; these match small holes underneath the theodolite tribrach. Metal Cases
