Be very careful if you fall into the catalog collecting pit!!! If you get real serious, then you will find out that there are sometimes multiple versions of the same catalog and you will feel the need to acquire each variation.
I have the 80th Anniv. catalog with the straight line on page 33 with a 1934 price list
I have the 80th catalog straight line version with the June 1935 price list
I have the 80th catalog with the .357 magnum on page 33
AND I have the 80th catalog with the .357 on page 33 with the 1936 price list and a typed note about pearl stocks not being available for the K-22 model.
So be very careful before stepping into this minefield.
