      Surprisingly, while many other makers have been content to allow their lathes to be re-branded for overseas markets, Myford were never tempted down this road - the only known exception being the application, in the USA, of badges proclaiming: "Allied AMMO 7" x 30" G " to some versions of a long-bed, screwcutting-gearbox equipped Super 7s of the 1960s. Of widely varying quality from appalling to reasonable, at least five different "Chinese copies" of the Super 7 are known, these being distributed, using various names including, in the UK, Australia and New Zealand. However, one rather fine (and improved) Italian-made copy has also been discovered, this being manufactured by the well-established machine-tool maker Minganti and branded as a MI-BO. The one example so far known was discovered in Canada for, unlike the better-known Taiwanese copies, one has yet to be found in the United Kingdom.
      At a guess the MI-BO would have been made in the 1950s, the use of the earlier "open" tailstock casting but inclusion of Super 7-like cross and top-slide handles being two clues. It's likely that the makers copied an ML7 made circa 1948 to 1950, the micrometer dials are of the MAKAK type, the headstock bearing are lubricated through turn-to-open wick-feed oil caps, ball-spring oilers are in evidence on slideways, tailstock and leadscrew hanger bearings and an early type curved leadscrew guard is fitted. Even the lovely little "Acorn" knobs on the tumble reverse and backgear levers have been copied (though in red rather than black plastic), together with the round knob on the leadscrew clasp-nut handle with its ring of fine knurling around the circumference. However, a few differences are apparent: the tailstock is longer with an extended base and that part of the casting through which the spindle passes extended at both front and rear - the latter possibly concealing a different retention method, the Myford "split washer" arrangement being clever and cheap to produce, but not without problems The top slide is fully machined all over -  just like those on the very late Myford versions - and bed-mounted rack is longer, running a good two inches closer to the gap in the bed.
      Minganti appear to have produced not only a very high-quality clone, with smooth castings and fine detailing, but, by using a double-step pulley on the motor to countershaft drive, one with 12 speeds running from 32 to 1200 r.p.m instead of the original rather slow six that spanned a rather slow 35 to 640. It might be that the headstock bearings are also bronze instead of white metal - Myford suggesting, in an
      Model Engineer Magazine report that the white metal bearings (by Galcier) had become too expensive and the substitution of bronze (as offered as a replacement in later years, required a hardened spindle. If you have a Minganti-Myford the writer would be interested to hear from you.
      "Minganti Joseph , one of the pioneers of the Italian machine tools, was formed in his father working abroad. In 1919 he began to produce their own letter-book presses, moulds for containers cachet and a small drill press . Within a few years the business grew and moved the shop in Via della Fontanina to a new factory in Via Ferrarese .
      He was always beside his wife Gilberte Gabrielli , who took charge of the organizational and accounting side of the business. At the Paris Exposition of 1928 Minganti presented the first lathe with hydraulic control and continuously variable speeds , the patents taken out giving him international fame. Then came other machine tools including drills and milling machines, as well as a number of special machines for the packing of cigarettes and production of bearings, wire mesh and, pistons. In 1936 , during the period when Italy tried to become self-sufficient in industrial production, the Company manufactured turret (capstan) lathes - models that proved to be of excellent quality and the equal of foreign ones .
      During the WW2, in 1943, the factory was hit hard by a bombing raid and subsequently the German command decided to confiscate the factory's machine tools and transport them in Germany, but Minganti fought the request to obtain the transfer of the machinery and of its engineers to Palazzolo .
      When her husband died during the difficult process of reconstruction and in the following decades , it was the wife Gilberte to lead the Company with intelligence and determination, qualities that were recognized with her appointment in 1964, as the first woman in Italy to be awarded the Knight of Merit of Labour.
      The company moved in the early sixties in a modern industrial complex, in Via Ferrarese, and contto successfully produce machine tools, precision grinding machines, vertical lathes and automatic."
