How to model an existing part on Solidworks

I am trying to model a part that exist to Solidworks as in reverse engineering (Without the usage of a 3D scanner).What is the best way to model it without any drawings. Please find the photos attached

Brute force. If you have a physical sample it's time to break out the calipers.

Without a physical sample, the next best thing would probably be a decent image of the part from directly overhead. This image can be inserted as a 'sketch image' which you can sketch over the top of to guide you in the construction of a good portion of the model.
