Don't know

I don't know what the horizontal adjusting screw is for on this new V block I just got?!?

That's a good question.

Dial indicator mount?

Dial indicator mount?

Oh maybe....but if that's what it is, it was poorly done.

Some sort of support or leveler should you need to set it up on it's side?

yup I think that's all it is... just a mechanism to change the angle of the block when its leaning on it. I guess I was overthinking it, (not a common problem for me)

I don't know what it's for but i have an old Starrett v block with that desugn. Model 567. The 2 on the left are Brown and Sharpe, similar design but no cross piece

Looks like you're right YYC

And only $315 USD, yikes

Interesting. At least I have a tool that "copies " a Starrett! That's as close as I will likely get!
I was almost too embarrassed to ask and show my ignorance but I feel much better now that others don't know for sure how that screw was designed to be used!

I've never seen one before!

I think they are called fish tails but have yet to find a picture of them in use. The only thing I can think of is maybe the jack screw can be adjusted in/out to act as a kind of an extended contact point for stability if the V block is in lay down mode? Good question. There must be a legitimate reason, they wouldn't go through the effort just for fun.
