1970-80s Celestron EPs

I've attached a pic of some older Celestron EPs that I purchased back in the late 70's early 80's. Does anyone know what FL the Orthos and the Erfles came in??

I have the 9mm and 12mm Orthos (12 in pic), and the 20mm and 32mm Erfle (20 in pic).

I would like to add something in the 4-7mm range for the ortho, and perhaps something around 15mm in the Erfle if they made them to round out the older collection.

Thx.

I have the 20mm Erfle and a 5mm Celestron Ortho. I believe there is a range of Ortho's and I believe I have seen a 32mm Erfle.

If you are interested in my 5mm for your set, I would send it to you. It is decent optical but from a cosmetic standpoint it is definitely used.

I have a set of the standard Meade Orthos from the same era (not the research grade models) so I never use the Celestron...

I have a pair of the 20mm erfles like yours. Great ep's. Too bad they dont make 'em like that anymore.
