They are the old style Sakae's - not a rarity exactly, but it's the old wide BCD so it's harder to find in good condition for low cost.
I am familiar with Helicoils (though I've never actually done one) - However- if it is not as secure as a new crank, I would think I may be better off scouring eBay for a new one.
If going to replace the crank then you don't need to use one with the same BCD.
