Rare PRESTON No 516 Patent Adjustable Spirit Level - 27 inch
A fine and very scarce 27 inch No.516 patent adjustable spirit level by Edward PRESTON of Birmingham.
Marked 'PATENT No348356' No516' with the PRESTON trade mark on the top brass plate. This patent was granted to Charles Henry PRESTON, youngest son of Edward PRESTON Junior, in May 1931, close to the end of the PRESTON history when the rule and level manufacturing part of the business was sold to RABONE in 1932.
Please see images for a copy of the original patent application drawings.
Also stamped 'TRADE MARK "QUIXSI" REGISTERED' on the side of the stock.
27 inch levels are quite rare and we have never seen a PRESTON No.516 before.
Mahogany stock, fully brass capped ends, two adjustable plumb levels, original trade label and 'blued' finish to the steel screws.
Apart from a few minor surface knocks and scratches this spirit level is in excellent original condition.
11/4 by 3 by 27 inches overall.
One for the collection.
