For the last year or so, I've been happily unloading my 20lb, 7-inch thick, childhood (1957-1980-ish) H.E. Harris Citation Album into 3-ring binders with Steiner Pages. Everything went fine until I got to Great Britain (which I had never paid much attention to).
Steiner apparently provides a number of different formats and groupings resulting in duplications or omissions.
Scott, in their wisdom, has numbered all the Machins separately with "MH", "NIMH", "SMH", and "WMMH" prefixes in-between the normal numbers for the Regionals (SMH!); very few of their color descriptions match what the Steiner pages say; and for the most part ignore phophorus banding varieties.
I've just placed an order for a Stanley Gibbons Concise Catalogue to see if that will help to mitigate the confusion a little, but to quote Han Solo, "I've got a bad feeling about this!".

Just wondering if anyone else has any thoughts or suggestions...
