Charger for Sony cassette walkman wanted.

[Arkwright 10]

I have an old Sony cassette Walkman that I received from my cousins. Unfortunately, the Walkman did not have a charger with it. I am not sure what the charger looks like, so if anybody can assist me in finding a charger, I would really appreciate it. Also, if anybody can provide another battery, I would appreciate it. The battery is known as a gumstick battery. The model number of the Walkman is WM-EX631. Here are some pictures.
