h&r litature

i have recently gained access to a large number of h&r catalogs which have been a big help in my research. i and still trying to fill some gaps; pre 1899, 1900 to 1904, 1916 to 1921, 1936 to 1939 and 1945 to 1949. believe it or not h&r issued a catalog for the year 1944 which i have a copy of.

any help would be appreciated
