That's a good looking rock but I'll weigh in on team re-cut. Or at least team explore recut.
There is a reason the cutter used these proportions, and it was not to make the most beautiful diamond. It was an economic decision. Since you are the lucky recipient of the diamond as a gift, the cost of optimizing its light performance is relatively small. And if you are not stuck on the carat weight or outside dimensions, tuning the stone up as needed to be a top performer has no real downside.
Personally, I don't think the mrb's of the 60's and 70's have a particular charm - not like the old mine cuts or old European cuts. They can be bright but lacking in the magic of fire. I think the stone will have more personality with a fuller crown and making sure the crown and pavilion angles are complimentary. It will have fuller expression of the best optics in a wider range of lighting conditions. That's the charm I would be looking for!
The problem with a large table and shallow crown is two-fold; the table facet throws excessive glare, and you need an ample crown to gather light from a wide range of angles and to disperse light into it's component colors on the way back to your eye (fire).
I would take it to an experienced and well equipped gemologist/appraiser and get details of the stone, including a Sarine scan. This way you have a good idea of what you actually have, so that you can make a well informed decision as to wether to recut or not. This may cost you less than sending it to GIA in case you decide to recut. If you don't recut, you may not need to spend the money on a GIA report if the document your gemologist prepares is sufficient for your purposes. If you do recut, your project should include a GIA report of the finished stone.
Good luck!
