Thanks for the replies so far.
I have added some more, and hopefully better images to my photobucket account. If you follow the link in my first post you will see them.
After closer examination the numbers on the inside of the trigger frame are 610 and the trigger is marked with a 53. The pictures show all the marks I have currently found. The bore is bright and shiny like it just left the factory, which helps me believe that the pistol has the original finish.
The holster has no stamps or markings other than the one shown below:
A small circular "cross" stamped on the inside edge of the flap.
