Still curious the many different vintage pan pie out there, what exactly is the number? gotten myself one with the cross hair and applied 3,6,9 & 12 markers, relatively rare perhaps? Crown running a little loose, not sure if a easy fix...
Not many but there is a lot of pie pans. Made over several years and many models and many variations in each model. Would be interesting to know how many exactly. Best constellation information found here http://omega-constellation-collectors.blogspot.com.au/
