That's the same setup I've got on my hull #7 - a cable bolted from cast metal box under mast, to keel bolt. Probably original.
I haven't seen one first-hand, but have heard of lightning strikes to sailboats on my lake (Chatfield Reservoir) that have fried electronics and in one case blown a hole in a hull.

There is a cast metal box which the mast sits in and which in turn sits on the big oak block. That box has a battery cable bolted to it which is attached to a keel bolt. Hope it works.

I have a 1976 30mki and we got caught out in a very fast-moving t-storm this weekend and I realized I should have done this when I bought the boat last fall. My mast step is not original. It is a big, fat piece of mahogany - which I envision blasting apart if the mast took a direct strike. The only idea I've had is using a steel ring clamp to attach a terminal on a very large gauge wire (maybe 2 gauge?) to the bottom of the mast, then run this wire a foot or two aft and down into the bilge to a keel bolt where I would have a second ring clamp hold the wire's terminal to a keel bolt. I worry about how this would look and I also worry whether it would even be effective. Anyone have a better solution? Thanks in advance. Hope you're all having a wonderful sailing summer.
