IMHO it is not of any particular plane cockpit. The Link Trainer ANT-18 was equipped with a full suite of standard flight and navigation indicators used for most planes at that time. Its main role wasn't to "pretend" any particular plane type cockpit but teaching pilots of the distribution of attention to instruments on the panel and their indications during a flight without visibility. So just a safe way to teach new pilots how to fly by instruments , no matter what aircraft could be flown in reality.
thanksI see . The Link Trainers were sold in a period ranging from 1934 through to the late 1950s. The ANT-18 - (Army Navy Trainer model 18) was in its turn, a slightly enhanced version of Link's C3 model. It was also produced in Canada for both the RCAF and the RAF with a somewhat modified instrument panel, where its model designation was D2.
