Artyom Babin (Артём Бабин) helped me acquire my Vertical (Вертикаль) Drop (Капля) (model ver 0103) from Vertical (Вертикаль) in 2022.
This Drop is 75 mm. long, 80 mm. wide, 29 mm. high, and weighs 109 g.
Model ver 0103 consists of a spring-loaded pivoting steel lever and a fixed anvil mounted between two3.2 mm. aluminum side plates. One side plate is stationary, while the other pivots on the lever axle so that it may be opened to admit the rope. The anvil is attached to the rear face plate with two rivets, one of which is extended with a mushroom head to engage a notch in the front face plate. Each slide plate has a l4.8 mm. attachment hole.
The pivoting side plate is printed with a left-curving up-pointing arrow with climber icon beneath, the Vertical logo, "VERTICAL," and "4 kN."
The Vertical (Вертикаль) Drop (Капля) ver 0103 is one of the following closely-related rocker-arm ascenders:

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
These
are small, reliable, but inefficient ascenders. There is
a significant lost motion with each step as the entire ascender
rotates under load. I wouldn't choose one of these for a long climb,
but their small size might make them attractive for short, remote drops.
To rig
these ascenders, open the swinging plate and bring the standing rope down between the lever and the anvil.
Close the swinging side gate, and insert a carabiner through
the holes. When load is applied to the carabiner, the rope exerts
a counter-clockwise torque on the lever, and the left side of
the lever squeezes the rope against the anvil. Lifting the carabiner will allow the ascender to slide up
the rope, provided there is enough rope weight below.
The Russian Turin Slip-Stop Basic and Vento each have a guide pin that the others lack. I don't notice the pin making much difference in how an ascender performs, but its weight is negligible so I see no harm in having it.
This type of device was invented by Soviet climber Yuri Gorenchuk (Юрий Горенчук). The C.A.M.P. Lift was the first non-Russian version, and it had teeth on the outside of the anvil
(see the Camp Lift page for the reason why) .
The teeth serve no function for the ascender whatsoever, but they were faithfully reproduced on all the Chinese copies.

Steel model ver 0104 is 72% heavier than aluminum model ver 0103. This is huge, enough that I cannot see why someone would prefer the steel model.
