1974 20ft center console(Barcone?)

[gvp5]

I am going to look at this boat and the owner knows nothing about this boat. He bought it to fix and it is beyond his abilities. He says it needs a floor and fuel tank and doesn't want to fix it. What other things should I be aware of when looking at this boat and was Barcone another company that used their hull designs? Thanks in advance, Greg..............
