Vintage Fisher Price circus Train 991 1973? Read

The train set was in a relatives basement and meant for trash. I only have the giraffe all pieces have a few blemishes such as fading stickers etc but there are no cracks. The giraffe is marked Hong Kong. The wheels on the train engine are loose and therefore do not move the whistle does work and has string.
Please feel free to ask any questions and I will do my best to answer.
