Since I had some spare (cloudy) time I decided to draw the TAL dovetail bar in a 3D modeling tool.
All holes are threaded. From left to right: metric M8, centering pin (8.5mm diameter, tapered at 45°), metric M6, 1/4" photographic thread, one hole with imperial thread similar to metric M8, metric M6, centering pin, metric M8.
In other words: the 2 holes at the center of the TAL dovetail are NOT metric.
