My guess is that the SP10B has the same body of the SP10A, only differing on the driver.
If so, the tube is not reversible, so the clip can’t be reversed as well.
I’ve done SP10A “half” review and took some photos here: DOUBLE 1 AND ½ "REVIEW": Sofirn SP10A and Sofirn SF14 *[added night / distance shots] .
The tube from the SP10A is interchangeable with the SF14, so my guess is that the 3 models use the same tube , with different head and tailcap!
Hope this helps
