M32 motorway The M32 was planned to be a key radial link through to the hub of a network of radial and ring roads within a rectangle encompassing Bristol. Other bounds of this scheme were parts of the M4 (north eastern side), the M5 (north western side) and the tidal reaches of the River Avon (south western side), the south eastern side not being defined by landmarks. The motorway was partly funded by Gloucestershire County Council and Bristol City Council, with a 75 per cent grant supplied by the national Ministry of Transport. It was provisionally called the Hambrook Spur or the
Leica M4 without a viewfinder was made as Leica MDa (similar to the Leica M1). Production of the M4 stopped briefly in 1972. Its successor, the M5 had been introduced in 1971. However, the relatively bulky and expensive M5 met with a cool reception, and sales did not live up to Leica's expectations. Production of the M4 was therefore restarted quickly until 1975. In the year 1975, a special edition was made for Leica's 50th Anniversary, and in 1977 the company launched the updated M4-2, which was based on the M4's body, but with a streamlined production process that reduced manufacturing cost.
