Has anyone used the Vinten 3471-3 quick-release plate? I'm scouring the internet but not finding much info on it other than from sites that sell it.

Vinten | 3471-3 ENG Quickfit Automatic Adapter | 3471-3 | B&H (http://www.bhphotovideo.com/c/product/238159-REG/Vinten_3471_3_3471_3_ENG_Quickfit_Automatic.html)

I'm wanting something similar to the standard Sony quick-release plate for a Vinten 5AS and EX1R and this seems like a good match.
