By the way, I pick the Brownie out of nostalgia for the one that my grandpa use to have long time ago.
Step 1: Open up the Brownie
Open up the Brownie which is quite easy since the camera is just little box with a small latch on the top that let us see what inside, after it is quite easy to a remove all the mechanics and the front lens as shown in the pics.
Step 2: Open the webcam and into the Brownie
See the pics for the details.
