Unless Canon built VL cameras with a place on the top plate casting for the release button that would permit a replacement knob (in lieu of the film wind lever) to pop up, this can't be a VL with a retrofit knob. Well, if I decide to buy it -- and I'm having a hard time convincing myself I need another Canon RF body, as I just came across an interesting Noct-Nikkor -- I'll be able to pull the bottom plate to see if it's a revised VT. And frankly, if I wanted a knob wind Canon, I'd be more tempted to try a IVSB or similar. I've used the knob wind on my Canon VT and it's less easy to use than the knob on my Leica III.
