If you look closely, there are chamfers on the inner edges of the sleeve already. That and not matching up with any of the Thompson diameters makes me think it's meant for the "Mavic" style BB (similar to the YST/Sunlite).

However, if the sleeve is removed, it may match up with the bigger 38mm Thompson.
