I think but am not sure that it may be a model 66. I bought it in the late 80's. It's a 6in barrel stainless steel. Serial numbers AGW0XXX where x's are remaining numbers. Also what would be the value of the gun? It's in great shape fired very few times. Last time it was fired was about 20 years ago and it's been sitting on a shelf in my house ever since. I can provide pics if needed.
Thanks
