Picked these 5 3/4” shells up from the local Metalspinning company, the same people who make the shells for LF Harris and Ace Classics as it happens.
These are spun from aluminium rather than steel and weigh very little. They only have one 5/8” hole for wiring in the bottom and no hi-beam indicator. I do believe that they are unique to British Ironworks.
