As far as Eurocarb, they currently only list V type Needle (VHB(T) 27-30mm) in the following type:
.
V1, V3, V5, V7, V9, V10, V12-V14 inclusive.

They have a chart with detail of the variations on their website:

You may find some elsewhere & @ a better price. Please let me know if you do.

What atomiser & slide are you intending to use?

Is yours the type with a non removable needle valve? I've never seen one that is removable.

Atom is 265n 7554.50 slide i dont know to much about these carb tbh , from memory i think it is removable but id have to take off the bike to find out

You have the closest that was ever made to being suitable for two strokes with the 'N' atomiser. So that's good.

Slides available are limited, but there is a modifacation that can be done, if required. You should be in the right ball park with a 50, though.

The reason I mentioned non removable needle valves & that is all I've ever seen, is that the fuel flow rate is restricted & you can only improve by opening up the holes so much. These days, with grunty, big bore barrels, longer stroke as even I have(!) there is a concern that suficient fuel can get into the carb to be delivered.

I have a carb, very much work in progress, that I have converted to take a two stroke atomiser from the PH range. There is still the problem of finding needles suitable, though.

I need to dig it all out soon & crack on!

I know what you mean about the needles took me a year and a half to find the v3 then panicked when i thought i was the wrong length lol
