I like the refractor congregation you have amassing in the lounge
I did eyeball this when it went up in the classifieds, would have been easy for me to make the 30 minute drive. I didn't research or appreciate the significance of this particular brass refractor until you posted a bit more information about it and as much as I considered it, funds wouldn't allow.
I felt the focal ratio was a nice progression for me though, F/9 to F/12 and then to F/15
