Scott Bonnar's 155cc 2 stroke Model 201/202 had 3 different magnetos fitted.
Up to engine number 201-4001..............Wico magneto [Pic 1]
From 201-4002 to 201- 6193.................Wipac magneto [Pic 2]
From 6194 onwards................................Wipac Magister magneto [Pic 3]
From this it shows that over 6000 engines were produced before the Magister was introduced. Old S-B employees remember that they had trouble with the Magister. It does seem strange that some engines without a Magister have a hole drilled in the aluminium shroud. This information comes from a late 1960s Spare Parts List.
