The data bases on TCR and TGT are vast. Most attributations in both books are attributed to the person that submitted them.
Both old and new authors have been very helpful in giving me that information.

You can get a pretty good idea of the reality of the attributation by who attributated it. If it is one of our "Boys" that can put names to initial chips faster than you can say "Jack Robinson," I go after it!

TGT table data base has helped me with illegal attributations over the years. It can sort by all fields. Allan Myers used to search it for me by say John Smith. If had a chip I could tie to John, I could see what other chips were used by or bought by John over the years.

These books are priceless to us.
If we see mistakes it is our place to call attention to them.
