Property of the late Jim Sandiford
c.1963 BSA 343cc C15/B40 Trials
Engine no. B40GB2039
The machine offered here was constructed around 1982 by the late Jim Sandiford and one of his mechanics as a replica of Jim's original works BSA C15/B40 trials, '776 BOP' (Lot 278). With its heavyweight B32 and B34 models becoming increasingly un-competitive, BSA had begun developing a trials version of the C15 '250' roadster in the late 1950s, before the latter's official launch. The trials C15 made its official debut at the start of the 1959 season when Jeff Smith secured a remarkable victory in the St David's Trial. Smith followed this up with wins in the Scott and Perce Simon events, and at the season's end the model was offered to customers for 1960 'as ridden by the works'. In production form the C15T incorporated many design compromises that were not inflicted on the works bikes, which continued their run of success throughout the 1960 season. The following year, experiments began with bikes using the 343cc B40 engine in the C15T frame, one such prototype winning the Scottish Six Days 350cc cup in 1963 courtesy of Jeff Smith. Currently carrying the display plate 'BSA 343', the replica was used extensively by Jim in classic trials, including the Pre-'65 Scottish Six Days on several occasions, and since his tragically early death in 1993 has been kept by the Sandiford family. The machine has been maintained and run every 3-4 months and is described as in generally very good condition. There are no documents with this Lot.
