Double Pan Balance

[EyeDrinkVenm]

Hi

 

Not sure if anyone can help me here. I'm doing a 3D project based on physics and dynamics. I wanted to know if anyone on here has, or could take, some photos of a double-pan beam balance. It could be a harvard trip balance, or an old one. From pictures on the internet, I am unable to see the underside of the pans and how they connect. I am setting this up in 3D and need to see all the components so I can model them, texture them, and then rig them and use rigid body dynamics so the balance will react similar to how it does in real life.

 

Here is a link to a low quality image I found if you are not sure what model I mean.
