Bob,
It's a model 1902 Round block from one of Rodney's castings, it's an internal hammer so a "horse of a completely different color".  I've been going to start a post on its build but my extra spare time has been spent on chasing shooting events in a different discipline.  I'll crash your post with a couple of pix I just resized.  It's going to be a 22rf so the original cast breech block wasn't going to work very well so I made another.  That and the barrel are almost fit... more at a later date. 
Pardon the intrusion.

This first photo is showing all the layout lines for the rear section of the right side of the frame.

The second photo is the rough finished upper section.

Third is the roughed out lower section.

This last is taken from the rear showing the curvature of the frame where the wood will hook up.  I had machined the rebate in the frame.  This rebate is for the wood tongue that engages the frame and holds the front of the stock in place.  I had some concerns that I went too deep and wouldn't be able to get the curvature at the back of the frame because of the corners.  As can be seen I have room to spare and could still add more radius, if I decide to.

WOW! You are a true inspiration in the details you are putting into form. This thread never ceases to impress.

Bob, you have some skills with the files!! Greg and Bruce here is my 1902 Webley about 90% finished. The lever kind of put me off at first, but it grows on you. It makes a wicked, fast light little rifle.

Got back on this little guy yesterday.  Most of this week was spent helping a friend profile a barrel blank to full octagon and getting it on the action.  He's never really done this type of work before so he's in for a real surprise treat when he starts stocking the gun, Stevens 44, from a blank.

This picture is just showing that the rough shaping is done on the action, and the screws are now timed where I wanted them.   

I'm starting to get ready to start the stocking of this gun.  I've sent to tumbler off for some welding repair.  I changed the position of the full cock notch and now need more meat, above the new notch, in order to cut the half cock notch.  I included here one of the pictures I sent to the welder so he knows what I am wanting done.  The tumblers quite small and will fit on the end of a finger, so he will probably have something too say about the size and how much trouble it was.  But, he alway does a nice job.

The next thing needing done in the prep for wood is some reshaping of the tangs in order to make wood inletting a little easier.  When originally machined the tang sides are straight.  I like having them tapered slightly for inletting.  So I hand filed the tangs with a taper, front to rear, of .003.  I would normally like a little more but the style and shape between top and bottom make it tough to do since they both need inletting at the same time and, the bottom of the front tang eventually gets a fitted cap, so it needs to be straight front to rear.  If it is not straight the cap might not be able to be kept tight.  This cap can be seen on the original gun in some of the first posts of this thread.  This photo is just showing the reshaped tangs......not really much to see though!

In this first photo I have drawn in the bottom profile of the stock, along with some of the detail of the grip area.

The second picture is the drawing with the chunk of walnut that will hopefully become the stock!

After studying the drawing, I came to the conclusion the lower profile line just didn't look right.  The flow between the upper wrist and the lower line just didn't work.  By adding a little more perch belly the lines work much better than the earlier drawing showed.....at least in my opinion it does!    At this same time I made the grip cap area slightly smaller in length.  The original lines can still be seen, as erased, in this picture.  Also can be seen in this last photo, are the grip cap, butt plate and all the proposed screws attaching them.
Bob

I'm in awe of this whole project.  In particular, how much better the slight perch-belly makes the stock is very instructive - i.e., even when one design works and looks ok, it likely never hurts to try some variations thereof before saying "done".
