[Frameworks] [Labos] "New" lomo tank filling with 16mm film

[Ethan Berry]

I have sometimes filled the tank through the drain hose using a funnel at
the end of the hose. Drain it as you normally do.
The "old" tanks that I have usually hold about 1,800 ml. I would guess that
the "new" tank holds slightly less.
If the spindle won't go up and down, perhaps spinning it would work for
agitation.
