Gon Gon Gon Gone Gone - the deepening mystery

I'm going to have to agree with Jason.
Somewhere in a box, I have a postcard that shows #9 leading the consist of converted gons at the fair. I also have a photograph that shows #69 pulling five, yes five, converted gons. So, if only three went to the fair, somehow - somewhere ... there were at least two more gons that were converted to look exactly like the gons that D&RGW converted for the Chicago Rail Fair.
There's still one more missing link to this mystery. I also have pictures of two converted gons that look exactly like the fair gons in Hesston, Indiana. BUT, there's an accompanying story of how bleachers were made in Alamosa from converted fair gon parts. So ... one way or another there are more than three converted fair-looking gons. Jason, I'll email you digital scans of these pictures - with the exception that I don't have any bleacher pictures.
One last question ... how did the GLR fair gons come up with the numbers 5, 7, and 9?
More useless trivia ... according to a picture in Adolph Hungry Wolf's book, showing a converted fair gon in a consist in Durango, these converted gons were put on the Silverton train. How many times and which dates? Who knows, but there is a picture.
It would be great to see a comprehensive accurate history of these amazing plywood beasts in the Colorado Timetable! They have certainly been well travelled.
