As far as I know they don't have the 1893 catalogue.
Holdings as far as I have discovered so far are
1893 1st
1894 2nd NAL MET
1895 3rd BRAD MET
1896 4th BRAD NAL MET
1897 5th BRAD NAL MET
1898 6th NAL MET
1899 7th BRAD NAL MET
1900 8th BRAD NAL MET
1901 9th NAL MET
1902 10th NAL MET BOD
1903 11th MET
1904 12th NAL
1905 13th MET
1906 14th NAL
The best place might be the Royal Photographic Society's library now housed at the National Media Museum, Bradford. The curator of collections access is Brian Liddey.
