Pardon if this is a repeat message. Iím messed up with a recently mauled hand, typing one-handed and really goofing up at the keyboard.

Jim, I canít thank you enough; after all these years I finally know what I have. It is exciting.

If my other post did go through, I made an error in which I said that the ďf-5Ē engraved on the body was wrong. Not so. I got the lens out of storage (itís been that long) and it turns out the lens uses the defunct British Uniform System of apertures. This one has Uniform scale 1.5 to 64, which is approximately f5 to f32. So the USA folks put the accepted equivalent and engraved it accordingly.

Again, my deepest appreciation for the information.
