Just in case you didn't find it, there are a lot of great .38/44 pics in a thread on the 1945 to Present section. Here is the link:

I have a 1937 vintage .38/44 Heavy Duty and am considering obtaining a letter on it. What type of information is provided in the letter. Is it benificial to have one or is it basically something that says that you have an authentic S&W product?
Thank for the info in advance!
