Vintage 1950's Marx Prince Valiant Castle With 5 Figures-Very Good

This vintage Prince Valiant castle by Marx is pretty incredible. I don't know if it has all of the pieces that originally came with the set, so I ask that you please examine pictures closely. I know seperate accessories were made for this set, and I'm not sure which are which. However, and castle with moat can be built with what's present.

All pieces have thier tabs and can lock together. There is some oxidation on top/corner of one section (pic included), but I also made no attempt to clean or polish this vintage set. Five original figures also included. The red caps for guard towers and castle walls are also all present and fit in place nicely, but a chip exists on top of one.
