Richard,
I have two Gibb turning blocks which I intend to deliver to Oxford on Tuesday, these I have replaced by a spinlock 5x block.
On the port side coachroof I still have 3x Gibb blocks, I may, therefore be able to give you 2 blocks later, as I would prefer to update my boat to all Spinlock.
I searched high and low in about four boat jumbles, including Beaulieu, but was unable to find any Gibb turning blocks
