Blackhawk S4 or not - please help identify this model

[garagesapien]

I'm interested in the vintage Blackhawk floor jack shown below, available for sale locally. According to the seller, it's a four-ton heavy-duty Blackhawk S4 jack. However, my research indicates that the S4 model typically includes a light fixture. Could this be a case of model misidentification, or were later S4 jacks indeed available without the light fixture? The seller suggests that the light fixture might have been an optional feature. Any insights would be greatly appreciated.

I found another thread that indicates not all S4 models came with the light, so I think I found the answer.

S4 standard does not have the headlight or the key lock on the handle. S4 deluxe has the headlight and the key lock on the handle.

Mine has the light (no lens) and the key lock. What's the lock for?

Never mind - I just saw an old ad that features the lock as a disabling function. It never occurred to me that you might need to lock up your floor jack!
