Hallo Bram
Apologies for only getting back now, was away for a while.
I had a look at the information you send, and like you, I have been unable to find differences. That said, I do not know why they were split into different types. We as referees do not assign KM or P numbers, we get it from other sources, like the Krause Catalogues, and I believe a new website from the new owners of the rights to the catalogues.
And there are some members who collect only one example of a KM or P number. Not all are as mad as some of us to go into every variable available. This is the resaon why I am inclined NOT to merge pages, unless I get absolute proof that the items are infact one and the same.
I have so many requests, where members want to split the same KM based on minor issues, and here I have the same reluctancy.
If our admin believe that we should merge the makes, I will support their decision.
Philip
