Help identifying this lens, please

[Hollis]

I made some new waterhouse stops for this lens. The range that I went for was probably overkill on the last 2 or 3 stops but I was on a roll. You can see I went for the nice curved kind but, well, its not that easy with scissors so i just stuck with the square kind.

Nice Hollis! I'd like see see what a shot with the f64 stop looks like, wonder if it would squash the swirlys?

[Hollis]

Yeah, Im curious as well. I got some new type 55 Ill try out here in a bit. Ill post after awhile.

Thanks Bernie. I used to live in Little Elm up off Eldorado and was back that way a few weeks ago. Not much to shoot there Im afraid...

Bueno, bueno!

I love the cardstock...nothing like a reality check for thinking about having them photoetched, laser-cut, electrodeposited, whatever other anal-retentive ideas I might come up with.

Even if it's not perfectly round, many lens apertures sure aren't either.

Centering I guess is the only thing needing a major effort.

Thanks for the reminder of how simple things can be.
