Looking at the pictures, they look like someone was playing with either a striker conversion, or an enclosed hammer conversion.
The action castings look to be identical to the ones I have.
They look very much to my eye like a High Wall crossed with a Borchardt (spelling?) action, but what do I know...
I am sure that the guys on the forum will have somewhat more to add.
There are a couple posts in the Forum Help forum that relate to picture posting.
The method that works best for me is to upload the pictures to a photo hosting site online (I use Photobucket) then copy the IMG code from there into the message that I am writing.
It's yet another thing to sign up for, as well as remember the passwords for, but has proven to be the most reliable, and uses the least of the forums resources. It has also proven to be a good place to store stuff tha I might wish to be able to access while I am visiting friends and may wish to show them.
