A note about "made in Switzerland"


If it's a mechanical measuring instrument (calipers, indicators, micrometers, intrimiks, etc.) made in Switzerland, chances are we have the spare parts in stock. These gages can easily be refurbished to meet the manufacturer's original specifications. Oddly, if the item is of hybrid origin with at least 60% Swiss stock, it will be labeled as "made in Switzerland.

A note about "made in England"


TESA does not provide spare parts for their relatively inexpensive and discontinued made-in-England dial indicators with the Brown & Sharpe brand name. These can't be repaired at this time and must be considered expendable. The Mercer indicators which used to be made in England are now made in Switzerland and are identical to Compac indicators.

A note about Mauser


Mauser calipers are part of the Tesa manufacturing complex, currently being fabricated in France. Mauser items are generally unavailable in the USA but could be imported on request.

A note about Hexagon something-or-other


The parent company of TESA is Hexagon SA of Stockholm, Sweden, with headquarters in the U.K. This company apparently restless with its own image changed its name to Hexagon Manufacturing Intelligence in 2016. Last year it was called Hexagon Metrology.
