Need some help from my head machining buddies

I’m getting the itch to buy something to improve my head seat valve angle machining. My buddy has he’s pretty sure a Peterson seat and guide machine. He hasn’t used it in over well over 10 plus years probably closer to 20 as he closed his shop. I honestly can’t remember what it even looks like but I know it has an air operated float table. Now if I would buy something like this can it be set up to do like 70-60-45-30-15 degree seats or 55 if I bought the cutters? He’s looking for around 2000.00 with tooling. He also had a mill but that would be to big for me. Thanks for any help.
