I wouldn't worry too much about having no lens board. It is fairly easy to craft a new one if you have access to the proper tools.

Perhaps a good starting-point would be to determine just what it is. 254mm.=10 ins.; 7 ins.=180mm. (more or less). Also, for what camera do you need a lensboard?

The hardest part of making a lensboard is drilling a hole of the correct diameter, and that isn't really hard. If the board is flat, like those for the "Graphic View" and all the "Speed Graphics" prior to the "Pacemaker," you can do it with a brace and an expansion bit. If you have (or can get the use of) a drill press, then a fly cutter -- available in any hardware store -- will get you through plywood, Masonite, hardwood or light metal.

You'll find useful discussions on this site of the wide variety of materials suitable for use in fabricating lensboards.

I think a 254mm. lens will be very useful on a "Crown," whether it's a conventional or a telephoto design. With the bellows run all the way out, your total extension is around 13 ins., and even with a conventional lens, this should get you closer than 6 feet, good for portraits.

A long lens like that also offers another lensboard option. If you can find a used "Pacemaker" board drilled out for a larger diameter lens, you can make a cover plate out of any rigid, flat material (perhaps 1/4 inch plywood), drill that out for your shutter, then mount it to the old board with four small bolts. The additional extension won't hurt a bit, and may be a benefit.

I have mine mounted on a Kodak Commercial View 8x10. The outer barrel of the rear element is 63mm and the retaining thread about 67mm.
You'll want to use it wide open for portraits.
