I built a Gigant WWII German glider. The model is very tail heavy and so I wanted to put weights in the nose so it would sit nicely on the wargame table. A visit to a model RR shop got these lead weights. They are used as ballast for train car models.
It took a load of them and I wanted them to look nice when the nose is open. So I stacked them up and built a box around them.
