advice on Cooke with stuck Soft focus

[Emil Schildt]

The early series II for full plate was a 10.4"" rather than the later 10.5", which gandolfi's lens was a very early example of. I cannot put an exact date on mine as they forgot to put a serial number on it! The exact position and detailed text is probably the best way to put an age on it? It also differs from gandolfi's as the iris scale is reversed.

.

just a note: mine (the stuck one) is a 14.5"

My 10.5" 3.5 is not stuck.

I'll follow your experience in the DIY

I'll post you the piston ring clamp if you like, Emil? You should use a rubber seal (I'll make one) the whole way round as yours has the original finish, whilst mine was pure cra*!

It was hard to believe the series II was basically the same as a IIE. It looked half the size of the IIE.

A comparison of weights (minus flange) showed an even bigger difference:

Series IIe (efl 10.5") 1,480g

Series II (efl 10.4") just 840 g.
