I am at the beginning of a RVI to RVC conversion of a P6 Series One Smiths tacho, The first issue is how to get the bezel off; soaked it in penetrating oil, heating on a stove, stretched the bezel rim a bit with a screwdriver next trying to turn it to and fro by hand when that failed clamped with grinding paper in a vise then by a large cloth covered pipe wrench (dont worry it survived; ), to get tabs in line with the slots, I guess. Is that correct ? If its impossible to turn the bezel what could by the issue ? and what the solution ?

With the slots lined up it will pry off if you insert a small screwdriver and pry between the case and bezel, NOT between the bezel and glass.
If you cannot turn it you will have to gently straighten a couple of tabs to pry it off. Beware the tabs break easily, do not over do it.
It will be stuck by the caulk that Smiths originally assembled the gauge with.
Scroll down to the bottom of this ebay listing for good information on which replacement seal you may need to put it back together. Do use a seal as if you do not the gauge might mist up sometimes.

Do you have to turn the bezel clockwise or counterclockwise ? To get the tabs in line with the slots.
The bezel completely covers the tabs so it is not possible to straighten the tabs.

All the Smiths gauges I have taken apart have the tabs on the bezel, and these are folded over a rim on the case. The slots are on the case. The tabs are usually not equally spaced, so you need to figure out which way to turn the bezel is the closest way to lining up the tabs with the slots.
I am not clear on this - The bezel completely covers the tabs so it is not possible to straighten the tabs.
Some gauges, I think Stewart Warner do not have any tabs on the bezel, the whole bezel is crimped to the case.
