This is another great sub model by Ukrainian company Mikr Mir “small world”. A little flash on the larger pieces, can easily be removed. Pieces fit together very well. CA+ is recommended for gap filling. There are 4 pieces on the spree that are not mentioned on the instructions. 6, 7, 13, and 21. May be some kind of escape trunk or variation on the dry deck shelter but I can find any reference to it in pictures of the class. This is a great scale to show fine detail and still be relatively inexpensive and easy to display. I’m not a fan of the Mikr Mir display stands. You have to glue it on or drill into the model to make it stand. They should replace these with a cradle style stand.
