Brent, Here is the sight I'd like to use on the miniature Martini but have never been able to find one. It's a Parker Hale Sportarget, I believe it is the model 10B. It appears that this sight was also made for a number of American rifles. I found a PH 16 with a cobbled base and had planned to make a base like the one in the photo but then moved on to using the cleaning rod hole with the Lyman parts. You are right about the BSA Model 8 and the PH target sights. They are hell bent for stout, tight fitted and precise. I wish the Model 8 was made smaller as the amount of elevation adjustment is excessive. It is a better choice than the Lymans for target applications.

Thanks Dennis! My adblocker wont work with photobucket, as it wants me to turn it off to view. Absolutely gorgeous workmanship, and style on all of the guns! I especially like the Rigby flats on the Rolling Block barrel! Were these milled inserts added to the barrel, or a Rigby collar added as Marlin used on Ballard Rigby rifles? Not sure I'd make a .40-65 in a schuetzen style, as it might not be comfortable with a Swiss buttplate shooting off your arm in that caliber. My Ballard Rigby is in .40-63 Ballard Everlasting, and with reduced charges it's OK, but I'd rather it was a .32-40 or .38-55 instead.

That is one cool sight and one very cool Martini. Thanks for posting that.

Vall, The flats are integral to the barrel and Morris created them on a 1.300" barrel blank using the HAAS CNC.
The Model 70 is a .375 H&H Mag and that barrel started from a large diameter Marquart blank. The barrel is a full ovate incorporated into a octagon that transitions to a round. It too was created on the HAAS and has an integral front ramp. sling stud, recoil lug and quarter rib.
All of the other barrels were also profiled from large round blanks on the HAAS.

Brent, I don't own that Martini but totally agree with your assessment.

Absolutely amazing thee HAAS machine can build those flats integral and get the round contour so perfect between the Rigby flats also! I have always been amazed how Marlin turned out the flats on a short tube and internally threaded it and the barrel to put them together. But this is even more amazing that machines today can do this in one piece and be so perfect!

I imagine it still require more than a bit of finish work~~

It all comes down to how well you program and machine the item. Morris has been at it some time. My guess is he gets a very good finish coming right off the machine. I spent a fortune on my CAD/CAM software and am still learning how to use it. Great stuff with huge potential but almost everyone underestimates the amount of work that goes into the programming and R&D portion. I bought an integrated program which is a big help. If you make a change to the model you do not have to re-write the whole CAM portion, usually just the surface that was changed.

Imagine the condition of a blank coming off a stock duplicator where the pattern was an existing stock just taken off the rifle. I've only seen this once and the work was done on a Hoenig duplicator by an experienced operator. The barreled action did not simply drop into the new stock. Corners in the inletting and final scrape in was needed and removing tool marks on the exterior and redefining the fine detail was going to be needed. And unlike wood where chisels, scrapers and paper are used to remove tool marks rather easily and quickly, removing tool marks from metal is a different problem.
The clean simplicity of the barrel profiles that you are seeing in the photos belies the complexity of the various tools and tool paths that are required to get to a point that file and stone artistry can finish the job.
"I imagine it still require more than a bit of finish work~~", yes indeed, Steven, it does.
