Barry - That sounds great! It's nice when I buy an Alembic and find out I don't have too much to do to it. That sounds like you made a great buy on that one. By the way the tortoise shell battery cover does not sound like the one that it came with. All of the older ones I've seen were brass. Although, I bet the tortoise shell looks great! I would leave it as is. Also, all of the older ones I've seen had the inlaid logo. It seems that was standard back then. I think that they started putting on the hand cut logo on the surface rather than inlaid somewhere around serial number 50 or so.
