Which removal tool do I need for this 16t bottom bracket? The bottom bracket that you see in the picture has a strange 16 teeth profile (3-1-3-1-...). 
I had this bike built a few years ago and I don't remember what model the BB is. I wonder what removal tool I can buy to remove and replace this BB.

I will list other components around the BB, which may help to identify the model:


track Miche Primato Advanced crankset (JIS)
Mash Work frame with BSA BB threading




Edit: After dismounting the BB, I have its manufacturer/model information: VP Components VP-BC73.
Looks like a typical 20 tooth (Park Tool BBT-22/32) tool should do the job. I'm not sure why every 5th spline is left out of this cup design, but visually the spacing looks the same.
