The models have been opened but never assembled with instructions and model parts still in box. Not sure if the cellophane on outside was removed to look at or just became old and removed.
The Howitzer box as writing on the back and as tape on one side of box and flap.
I am presuming the Howitzer was made in middle 90's like the Tank which I found a date on the internet for in the mid 90's
Both models have the instructions and spurs with pieces still attached.
