The Midas SSII and the Canada Dry SSII both are Midas built SSII's.
From what I have learned from Jim Allen and John Glancy, we know of at least 50 built, but suspect more will be confirmed before it is all over. Tim Smolinski is another great source for the Midas SSII history and information, he has been collecting them for years and started the Midas SSII registry.
I highly recommend you buy the Scout Encyclopedia for a complete history of all Scouts and the models produced.
These were sold in a range of colors, dark brown metallic being the larger number produced, but there were blues, blacks, reds, etc. The list of colors will probably grow as we find more of them.
To date, I believe they have confirmed 16-18 still in existence. We suspect there are more and will probably see more of them, as the word gets out on what to look for.
So how do you know if you have a Midas SSII?
1- get a LST ticket- there will be a notation on the top left hand side showing it went to Midas
2- there are specific designations on the line set ticket regarding Midas options:
Contact me with your Scout's information, and I will be glad to help confirm what you have and let you know if yours has any oddities that make it unique!!
