I can recommend this catalogue.I previously purchased Machin lists from this Ebay seller and also have the PDF version.
Before you spend money on a machin catalog check out the adminware site.
I have a PDF version 0f a prior version (dated 2020). It does net some information out very well but it is not as complete in some areas as other sources. For example, the 2½p scarlet is often listed with very thin, thin, and thick values but this catalog only lists two.
I have used adminware's intermediate pages as my foundation and once you put the spaces in a tabular format like the Burges it makes sense.

For those interested this new catalogue looks quite good and reasonably priced. Probably available from your local dealer or on Ebay here.
