Thanks for the info both on the parts and condition of the hammer.
I will look into the links that were supplied and interchangeability of A-5 parts.
Just a quick word of praise for the help that has been provided via "The Firing Line Forum". It has been a wealth on information on specific concerns for the guns I own, it has also provided me with insight into issues that I wasnt aware of.
Great is the day that I discovered "The Firing Line Forum".
