Help identifying resaw pressure rollers

I was in a pro shop this week and got to see their resaw setup... I was wondering if anyone can help identify these feed rollers -- I can't find anything similar to them anywhere. They were paired with [this Laguna power feed from around 2010](https://web.archive.org/web/20110706055635/http://www.lagunatools.com/accessories/Power-Feeders/Laguna-Power-Feeder) \-- but the Laguna site doesn't show these particular rollers.
