S&W 38 Model 10-7 Custom Larry Smith Revolver

I have just acquired a S&W Model 10-7 38 special revolver that was customized by a Larry Smith as engraved on the 1" dia. heavy barrel
http://www.midcoast.com/~antiques/smithsw-38.jpg. Can anyone shed light on larry Smith or this pistol? Is it a special target pistol. It still has single and double actions.

Many Thanks,
