Too funny! That made me laugh out loud.I was thinking along the same lines. This thread is starting to sound like an episode of Finding Bigfoot. A bunch of guys analyzing grainy photos and measuring evidence to make a debatable identification.The actual drum obviously exists, and Ringo is still with us. This shouldn't be too hard to settle.
There is actually a thread about this on the other forum that barryabko linked to. The guy who set up the drums has taken the measurements and knows them but does not yet have permission to disclose the details so you're right the definitive answer is there.
That being said the same topic (depth of the drum) was brought up in that thread and he did ask what other people thought it might be based on seeing the exhibit and viewing the images.
I actually did my analysis before I even read that whole thread really just out of curiosity and for the fun of it. I did some research on it awhile ago at a time when I got it in my head to build the "perfect" Ringo Ed Sullivan kit and learned about the controversy around the true depth of the JF shell. While I quickly got over my compulsion to build the exact kit, I was left with a curiosity about the shell depth and a desire to one day find out the exact specs...
Besides I like screwing around in Photoshop to keep my chops up. I often invent challenges for myself since I don't get to use it in my job very much anymore but I like to stay up to date on it.
