I wish poeple would give me such 'stuff'!
I have a Gundlach 12-21-28 (possibly 12-19-25?) here that I use on 8x10. It's a fine lens even converted.
My few comments, worth as much as you pay for them
Good luck finding a flange or nuy for that shutter. I doubt it's standard in any sense, but could be. You'd have to measure thread diameter and pitch and then go searching. Undoubtedly, SK Grimes could make one for you at a good cost...
If you're happy with B&W film, use a monochrome filter on the converted lens. It will sharpen it up quite a bit.
As far as using on your Speed, the 7.5 is no problem but after that you'rte in trouble. If you try to follow what most say and remove the front element, you'll never make the 12" for infinity focus. With my Gundlach (and the T&R's), I have used the single element in front of the shutter and found absolutely no difference in the negs. Your Gundlach should be the same thread front & rear so if you want the rear element, take off the front and replace it with the rear. This will allow you to get the 12" infinity on the Speed.
The 18" is just far too long for the Speed...
Worth and quality depend entirely on your particular lens/shutter combo. Some aged well and some didn't. For me, the Autex shutter would drop it's worth quite a bit. For someone else, who knows? They might want the older original shutter? Then there's the cells themselves. Do they have any separation around the edges? Scratches or marks?
Wihtout seeing it and testing the shutter, the worth could be anywhere from 100 to maybe 250 depending on the market. If you're going to use it and enjoy it, it's worth a whole lot more!
