Thanks for the info. That pack is awesome. I've seen it before but always assumed the W575-1's were also sold in strips as they are usually referred to as strip cards. Looks like a bad assumption. You are correct about the Koester bread cards, but that is not relevant here as the Marranville was not a part of the Koester bread set. Details on the Koester bread set can be found here
