REPAIRS: Long Island Indicator Service is an authorized repair service, fully qualified to perform professional repairs on Standard Gage and Dorsey dial bore gages. SALES: The newest models of Standard Gage dial bore gages are manufactured in Switzerland by Tesa, the manufacturers of high-end Etalon, Compac and Interapid gages. Dorsey (USA) makes an excellent look-alike with the same specifications. The same indicator is used for Size 2, 3, 4, and 5 dial bore gages. A slightly larger version is used for bore gage size 6. A simple hex screw will fasten it to your various measuring heads. If you don't use more than one head at a time, you can save some money by using one indicator for all your measuring heads. You might also want to buy a new indicator simply to replace an old or defective indicator. Perhaps you want to replace the obsolete "made in Poughkeepsie" indicator with the new model made in Switzerland/Germany. You can also convert your metric bore gage to inch and vice-versa. Digital versions are also available with the option of converting your dial bore gage into a digital electronic gage. 
Bore Gage indicator model D1-20241-B-1 Your dial bore gage indicator consists of everything shown in the accompanying photo. Simply unscrew the hex nut, insert your measuring head, and hand tighten. Don't use tools other than a hex wrench to tighten the screw because you'll invariably over tighten and ruin the thread, in which case you'll end up having to buy another indicator. Also available: spare parts for the bore gage indicator including crystals and other easily replaced parts.
