Hi All, I wonder if those of you with straight lug Speedmasters and a set of measuring calipers might be able to take a reading as shown in the pic below. Both left and right measurements please, as laid out below. ( left being the non crown side) I'm trying to put together maximum and minimum case data If you'd rather not post the results please send me a PM. I appreciate your help as always
As already visible from your picture, the extreme outer edge is hard to measure. I think I read 2.1 mm on my 105.003-65. If I place the caliper on the spring bar, it's already 2.5 mm.
