I saw one of these for sale and was curious if they are considered "scarce". Anyone have any idea as to production years? Is this a "Terrier"?

Yes, the Mod. 32 is the "38/32 Terrier". 5 shot 38 S&W, (not 38 Special). They were produced from 1948 to 1974 on the "J" Frame. The Pre-war 38/32 Terrier was produced from 1936 to 1940 on the "I" Frame. There are some made Post War on the "improved I Frame" before it was changed to the J Frame.
