Could be, maybe something will show up. I have a bunch of old ads and introductory info saved, including now the one you just posted. In another thread on a similar subject, somebody smarter than me posted an idea that sounded very reasonable. This is not a direct quote, but it went something like this: 'The reason S&W quit advertising that .38-44 was OK in the K frames probably had to do with marketing. They had rather sell someone a new .357 magnum than have them produce near magnum performance in their existing .38 Specials'. That seemed to make sense to me.
