John at Keltoi Gaelic Clothing makes a great diced hose as I have personally discovered through ordering and recieving some. No pictures yet, sorry.

I also have a couple pairs of Norcalpiper's diced or triced hose, shop named skyehighlandoutfitters dot com.

These are all wool and custom knit typically, although your red and white should be more readily available as a stock item from somebody. Quality costs, so expect to pay well over $100US for a pair.
