Caveat:
It is assumed in the listings presented below, that when tools have corresponding descriptions in different C. DREW catalogues, that they will also have the same dimensions and weights. This assumption may not always be correct.
The listing for caulking wheels is stamped "DISCONTINUED" in at least one March 1, 1953 catalogue; this suggests that caulking wheels may Ihave gone out of production shortly after the catalogue was printed.
