Nice! Out of a Mil Mi2 helicopter, I presume? Are they new old stock then, because they stopped making the Mi2 in 1985.
Looks ideal for a boat, doesn't it? Probably runs on anything you like too, being Russian. Kerosene, Paraffin, A1, Jp1 or Spry 'Crisp'n'Dry'!!
Boat: (Noun) - A hole in the water, lined with fibreglass, into which you pour money.
