The Stewart-Warner tool set I have for removing, and installing the bezels is built solely for this purpose. Picture this: A 1/4" wide flatblade screwdriver bent at about a 80 degree angle from flat. The blade is then ground at about a 1" external radius to where the outer sides of the blade now have no sharp sides and just meet the underside of this blade. Basically looking from the side of the tool you have a crescent shape with a flat bottom. These bezels are very soft and the edge of this tool is pushed under the retention crimp of the bezel. The tool is then "rocked" back and forth to pry open the crimp. The tool is then shifted to the side and the process repeated until you can remove the bezel. The second tool is for rolling and straightening the bezel where it was removed. This is a fashion of two gear driven rollers that you stand the bezel edge into and crank the roller handle. This causes both rollers to squeeze the bezel material and rolls the dimples back out that were incurred from the prying to remove it. This is adjustable for pressure applied to the rollers. The third tool looks like a large socket from the exterior. You simply place the bezel back on the instrument and using a small arbor press, slip the bezel and socket assembly into the press and lightly apply pressure. This socket has three angle ground into it's interior. The first angle starts to fold over the bezel, the second finishes the fold, the third does the crimping. It is important to not apply too much pressure as things can break. As mentioned, the bezels were steel and "flash chromed". This is a very short duration in the electroplating bath due to both cost and to retain ductility of the finished product. Unfortunately, durability suffered and rust is prevelant. The bezels were offered in stainless steel as aftermarket replacements, but never offered as OEM to the best of my knowlege. I don't know how many hundreds of SW instruments I've rebuilt as one of my high school jobs was in an instrument shop. Most times to rebuild a mechanical speedo or tach, the easiest was to just toss the guts and replace complete, but you could still get the stuff new. Now, I wouldn't be so certain. You can still get new bezels from the current owner of the Stewart-Warner name but they are slightly different with a flattened face. Rather than the coming to a dull point, they are flat on the face but still look acceptable. If you were replacing them all, hardly anyone would notice they are not period correct. You can however have your originals rechromed but there would be little to no cost savings. Rob
