Kacper, they are great kits and with some excellent accessories! I have just recieved the Battle of the River Plate set. 4 kits for 22.5 Euros (£19), including postage, direct from JSC Poland. I'll do an unboxing later.
Meanwhile, work progresses with the deck elements. Various hatches, lockers and vents fitted before moving to the attachment of the hull sides and 01 decks.
Having fun with this.
