An early Manaslu stove. It is the compact 121 size.
It appears to have been well-used, and even comes with a needle cleaner. The body is tarnished, but still retains a good amount of shine. The pump cup has been replaced with a new one. It produces plenty of heat and is very practical. The mechanism is simple, so it's easy to use and unlikely to break down. If you've been looking for one, this is the one for you.
