Having looked at that catalog picture I find that my lever is NOT in fact an ABI model! My apologies for a misleading advertisement.
I was going on what I was told when I purchased the boat
. So, I do not know who produced this device. It is made of heavy (6 mm) stainless plate, the eye-to-eye length extended is 360 mm, closed 280 mm. The hook will accept up to 16 mm (5/8") pins and the other end has 13 mm (1/2") diameter pin size. I was using it to tension my inner forestay which is 7 mm Dyform wire. My new setup does not include a lever, so this is surplus to my needs.
Attached find photos of the device.
Again, I'm sorry to have mislead everyone.
