There are a few members here who are very knowledgeable about Colts. Just give them a day or so to see the post and respond. If you don't get any responses, then try the Colt Forum at http://www.coltforum.com/.
We [civilians] sent many handguns to the UK during WWII . .After WWII they took them all and dumped them into the sea !!
