Hello,
Just out today from the ever busy Black Cat Models mini workshop are two diorama accessory sets:
Barges tanks
DD350012 barge tanks

These tanks were usually found on US Navy barges.
ABSD floating drydock elevator
DD350013 ABSD elevator

These elevators were found on each side of the large US Navy ABSD floating drydock.
More new kits and accessories very soon!
Meow!!
Ben
