There was actually a special run of the Model 60-15 chambered in .38 Special made in collaboration with Talo around 2015. I don't know how many were made, but I've got one. It's the Pro Series with a 3 inch barrel, adjustable rear sight, and front night sight, and very nice wood grips. The barrel is marked "S&W .38 Special +P". Current production is only .357 Magnum.
I remember the introduction of the original Model 60. It was priced at $110; at the time, a blued Model 36 was $65. In spite of this, supply could not keep up with demand and there were 6 month waiting lists to get one. It was not unusual for Model 60's to change hands for $200 in 1966. That's close to $2000 in todays dollars. I acquired a 1967 vintage Model 60 about 5 years ago that I shoot frequently. In like new condition with diamond stocks, I considered it a bargain at $650.
