The color and numbers of this helicopter's registration changes constantly in the film, between black and white numbering, and between CCCP-26540 and CCCP-25640. Probably indicating that more than one airframe was used. Of these, only CCCP-25640 appears to be a real registration, associated with c/n 3055.

It remains preserved at Central Air Force Museum in Monino.
