Best old school keyboard for shoulder studs?

So I went to Walmart today thinking I could buy a cheapie keyboard and use the keys for the shoulder studs...WRONG!

The shape on the newer keys on the keyboards are totally off.

Is there any particular model or brand of, I'm assuming, an old school keyboard off Ebay that I can use for the shoulder studs?

There isn't a specific model or brand (yet) and some used keyboard keys that are close in shape to the 'original', while others made replicas from one piece or multiple parts layered and then sanded to form, using different materials in different ways, starting from sintra, wood or metal (and so on).
