Bridgeport Milling Machines email: Bridgeport Milling Machines Handbooks, Parts Lists and Spares for most Bridgeport machines Although in the UK one often finds ordinary horizontal and horizontal/vertical millers badged as being by Bridgeport, these were actually made by, a Leicester-based company owned at one time by Bridgeport and responsible for producing copies of the ' real American Bridgeport turret miller ' (the Serial number on these models should be on a plate inside the column door - the last 4 digits being the date of manufacture). Adcock and Shipley also manufactured the later.

Although the on the corner of Lindley Street and Capitol Avenue, Bridgeport in Connecticut, was demolished in 2010, spares are still available and will continue to be so for the foreseeable future. Today the original form of the Bridgeport is, to distinguish it from later computer-controlled and larger models, referred to as the 'Series 1'. It was first manufactured in 1938, by two immigrant Swedish engineers Magnus Wahlstrom, a toolmaker, and Rudolf F.

Bannow (died 1962) a pattern maker and radio ham. The two men had first met in 1928, when Wahlstrom had called to buy wooden loudspeaker parts from Bannow, then president of the 'Bridgeport Pattern and Model Works'.

By 1929 they were in business together and attempting to develop an electrically-powered hedge clipper; however, when this idea was abandoned they began work on a vertical-milling attachment designed to fasten to almost any of the hundreds of thousands of plain horizontal millers then in use. This accessory, the first of many, become known as the ' Master Milling Attachment ', and was originally designated by the partners as their 'Model C'. Smartly presented, with a polished aluminium housing, it was well engineered and equipped with a heat-treated and ground spindle running in four precision, pre-loaded bearings (with those at the pulley end allowed to 'float' to accommodate expansion and contraction of the spindle) and with a quill that accepted (as standard) 3-inch long B-3 collets. The head was powered by a 1/4 hp motor that gave, in conjunction with 6-step aluminium pulleys, speeds of 465, 675, 1000, 1500, 2140 and 4250 rpm. The first production example was delivered in 1932 to the Atlas Tool Company of Bridgeport and the head continued in production long enough to become known as the 'Model M' when eventually fitted, some years later, to the first Bridgeport milling machine. The partners, however, were not alone in the conversion market and by the 1940s many similar attachments were available, the best-known of which were the ' from Racine; the from Michigan; the ' from Detroit and Kearney & Trecker with their Dalrae-manufactured ' and ' units. One special version of the Bridgeport Model C was made for use on precision Hardinge horizontal millers (early versions were badged Cataract MD5) and these heads can be recognised by a Serial numbers beginning with the letter 'H'.
