These came off of a really nice early ti mountain bike. Probably a first run Kona. They look like Cook Brothers but perhaps pre '87? Not even cracked at the square taper. Never seen cranks like these with a closed pedal bore.
Just looking for any info. Thanks!

They look really nice but the closed pedal bore seems like a bad idea. I try to use the hex interface on the spindle to lock down my pedals with a torque wrench.
They look like old Cooks Brother Racing cranks. But, that closed pedal isn’t something I ever saw with their cranks.
They are Grafton cranks. Later named Topline cranks. I have a road bike set with a Campagnolo bolt pattern spider.

Most of the Cook Brothers cranks I’ve seen had a bigger “eyelet” sort of shape at the pedal threads, with a skinnier arm. And yeah, I don’t remember the closed bore on the back.
That said, [this guy](https://www.ebay.com/itm/385504590915) has the same cranks and says their Cook Brothers, but I don’t see any evidence for that and the price is absolutely ridiculous.
Someone else already identified them as Grafton. They’re Grafton Speed Sticks
