Champ mid collection

[Raceman]

With the small snouted, exit out the back mid that I got from Parker this week I think I have at least one of every style Champ mid that Merc ever made (including one I was unaware of until Parker sent it to me last year) EXCEPT the one that had the box straight out the back of the exhaust chest and meeting the mid in the top of the snout. Anybody know if any of these avoided the crusher and where one might be today?

Raceman...How bout a tutorial with pictures and dates of manufacture... ;)

LR, I can put em in chronological order, but can't put years with em. I'll try to get some pics of em over the next several weeks. They're kinda scattered around in my junk.

That would be great. I am sure chronologically would help.
I think there were more styles than most folks think. Every once in a while I will see one for sale that is a little different than how I remembered them. Then I realize I have no clue how to ID them by years... :(
