as for the other guys on your list, here's what I have on my checklist (only two of which I own):

WaJo - 1907 Weiser Cabinet, 1907 Weiser PC, 1908-09 Carl Horner Cabinets, 1908-09 Rose PC, 1908 W601 Washington Premium, 1909 Barr-Farnham PC, or 1909 T204 Ramly

For Matty, there are also some team photos that were likely re-struck at a later date but they were taken during the period, so it's possible that one/more exist. I've only seen re-strikes for these at this point so they don't count in my book (yet)...they are 1898 Honesdale Baseball Team Photo and 1899 Bucknell Team Photo.
