Although I have never done any of this kind of work, I shot those pix for Joe Smithson and currently have three Ralf Martini integral barrels in the shop all set-up for Talley mounts.
Smithsons mount is quite remarkable in that it is the cleanest instalation I've seen for adapting older rifles to modern scope. that said it is not the easiest to remove and replace he scope from because it must slide on and off straight back or forward. Kind of the opposite of claw mounts, there is NO tilt factor so scopes with objective bells and rear sights can get in the way of each other. Seems obvious, but until you ding the bell sliding it back to hit a rear sight...
The breech must be opened to remove/replace with a double rifle, better with the brls removed. The slotted mating of the rings to the bases don't allow any tightening for wear. (also note, this rib mount has the male part on the brl, normal bolt rifle mounts would have the male on the ring.) Last I heard, Joe had only sold a few components to gunmakers for installation outside his shop. Not cheep, but very high quality.
I've got more experience with talley although the only field use on my own rifle and I've never removed the scope except to upgrade it once.
Talley's, when removed, offer some very sharp corners and edges that somewhat dangerous and might be considered unsightly. Here's a pic of Talley mounted on Hagn brld action.
A you can seem Ralf mills his with the rear base cut from the brl cylinder.
(These pic were taken to show action remodeling.)
I have found a problem with eye relief, even with Leupold 1.5-5 which is my favorite scope for modern rifles. It had better be mounted as far back as possible, preferably with the rear base on top of the aciton.
I have no inclination to make recommendations, just thought these pics might be helpful. Let me know if you want to see somethign else. also good ideas for stylish ribs. (Im also revealing that I'm th worlds worst typest but have a ton of other things to do at the momnt and am only going to do minimal editing, whic I usually spend as much time as I do writing!)
Best,
