Travis and John,
Many apologies for the delayed response, and it seems like you might have all you need. John was very gracious in loaning me the Crass and as a result, I have several hundred photos and diagrams(mostly measured and spec'd out) of the mechanism in the gun. I will gladly share this information with anyone who is interested in it. Please feel free to reach out to me and I will make it available. I am afraid that it is quite a volume of information, and might be a bit of a burden to post up here.
