Thanks , Kevin. After I didn't get any response for several days from my post , I did contact Smith. I talked to a "historian". He was very informative , and no cost for the info, I might add. Says , my Smith was a limited run.....is a L frame round butt , 2 1/2 incher with red insert front and white outline rear sights. Being this gun was from the mid eighties, they didn't normally make them like that. Anyway, I pretty much found out what I needed to know........thanks for your response. regards, irold
