Operation OK. The battery cover has been repurposed and modified from a late-model James carburetor cover, and I made it myself. There are no problems with playing with it. I am also selling other items → #Sasachan I check the operation of toys before shipping them. Please refrain from purchasing if you are sensitive to used or vintage items. Welcome to set purchases! I'll make it cheaper. If you negotiate before purchasing, I'll discount it a bit for your child, even for a single item.
