Another JFS imported Lerebours lens to-day on the bay. Exactly the same petzval that I have!
This one has a slightly later serial number (They use Lerebours serial number series) 7081.

I think this is near the end of lens edge numbering - or perhaps just after it stopped.

Obviously, it is now general knowledge that J.F. Shew got his lenses from Lerebours so my bid was well under two others.
If the winner sees this, it would nice to know whether the lens marking had ceased? Ebay 292276743237.
