Well, yes. That's why one is Scott and the other is Walsh. I'm not aware of a concordance between the two. Have you considered starting with Scott or Unitrade, and then moving over to Walsh once you've gotten most/all of the "basic" types?
There is another catelog called Unitrade. It mirrors the Scott numbering.
Both are not as comprehensive or detailed and don't change much. Therefore since the Walsh catalog is more detailed, it has to have a different and more expansive numbering. For example, look at the number of entries for Newfoundland.
