    With such lenses its probably going to be a matter of making your own. I do so from either thin black plastic or card and its a relatively easy thing to do. Alternatively pm me you email address and I will pass it on to a friend in Dublin who might be able to give you a contact who can make such stops.

    I don't know if this will help, but I stumbled across this site last night:

    http://www.re-inventedphotoequip.com/Home.html

    He sells a simple meniscus lens in a PVC tube, and provides a bunch of waterhouse stops for them. He doesn't list the stops for sale separately, but if you contact him, he may have something that works for you, provided he can ship internationally.

    Cool, I didn't know that. I've been working on 3D modeling a piece to front mount my packard shutter using Cokin P adapter rings (and modeling a few Cokin P adapter rings for unthreaded lenses) when I stumbled across his site where he adapts packard shutters to Cokin P. So it looks like he had the same idea, which is cool. I'll probably keep working on my model just because, but its good to know that it isn't a crazy idea.

    The single-element macro auxiliary lenses for 35mm cameras are meniscus/Wollaston lenses. If you get them in 58mm, they screw right into the back of a Compur #3 or Copal #3 shutter. If you've already got another lens with that size shutter, you have a working modern shutter and adjustable aperture already mounted on a board that fits your camera. And you can buy a set of 3 or 4 different focal lengths for well under $20.

    Is 1560 a Petzval and does it have a Waterhouse stop slot? The only Grubb lens that I have with a Waterhouse stop slot and an actual original stop is an Aplanatic Doublet from the 1880s. 1560 is much earlier, but it could have a slot. I have original washer stops for a number of my Grubb Aplanatics, but they are all bespoke sizes made to fit the 'pill box' on top. One of my sets has f stop numbers marked in pencil, but those markings were obviously done much later. It also has the native aperture of the lens written inside.

    I believe that 3 D modelling using digital methods might be the best way for you to go.

    The B2 is a Petzval. I've made a plastic Waterhouse stop for mine and will dig it out and photograph it when I have time plus I'll add the specifications too.

    That is, of course, correct, Paul. The point I was trying to make is that Grubb lenses were not in my experience, I have 7 of them, made in standardised sizes. So, any fittings such as stops or baseplates have to be bespoke. Lenses made in the 1850s and 60s were long before the standardised sizes and fittings which we became used to during the 20th Century.

    I made some at the expense of a couple of 5x7 aluminium plates they are working nicely
