I have an aquaintance who makes fitted, velvet lined wooden presentation cases (similar to those the factory provided for percussion models before the turn of the century). They are beautiful, he can do whatever you like. I have loaned him some of the Colt enclosures that I have so he could make repro's for inside the lid.
With your OK I can give him your Email address and you two can hash it out. Give me a few days to contact him, though.
I just spoke with Bill and learned that he has left his other job and is making cases full time now. He said to just go to his new website www.billscases.com and you will find ordering instructions and his Email address there. He shows a picture of a cased 4" Python for $160.00.
I have seen several examples of his work and they are 1st. class, plus he's a Colt nut like us. /forums/images/graemlins/tongue.gif B.W.
