Oh. Well that was silly of me. Just remembered that I was in the middle of my own '93 based project and that I had to do some rink modifications anyway and a square crease would be a nice look for it. [not era specific other than "older"]
This is the location of the the tiles and the hex offsets for the top crease. [still have to reverse everything in the hex code for the lower crease and fix the center ice logo, but it's a start]
