I found all the casting numbers as described in the link which was more than helpful.
The problem was that I had couldn't decifer what they all meant.
Like everyting else in life, it is easy if you know the answer.
There is so much misinformation on the net. As you said there are a whole bunch of theories out there about the CON 3 which doesn't seem to have any purpose which only added to my confusion.
I knew I could find the right answer from Stovebolters like who knew the real story.
Thanks again for your help. Without it I would still be in the dark.
