I was hoping you'd get it for less but it sounds like you got a nice, complete, and working set of gear. Have fun with it!

Use the battery case of the flash as a handle. Some Graphics were set up with a solonoid mounted on the lensboard. There's a button on the back of the battery case. If everything is wired up correctly it'l actuate the solonoid which has a mechanilal linkage to the the "front shutter" in the lens.
Make sure that the "rear (focal plane) shutter" is being used make sure that the front shutter is set on T and open. Likewise, when using the shutter in the lens make sure the focal plane shutter it set on T and open!
Forget about flash bulbs. If you can find Edison base bulbs they'll be several bucks each! Also they're way too bright! With ISO 100 film you'll be shooting about f/22 twenty feet from your subject.
The 127mm f/4.7 Ektar is a nice lens but barely covers 4x5 stopped down. Press photographers liked them because it covers an angle about the same as a 28mm lens on 35mm. It was really designed to cover 3.25 X 4.25 inch film.
I have been using this tortilla method mentioned in another thread and I have committed multiple Bonehead moves to screw up TWICE!.
gdi; thanks for these comments. I used trays and got good results but thought about the tortilla method but decided on a Yankee daylight tank instead. Its on its way from Freestyle.
That's a nice shot you posted. I'll be looking for more. My first efforts were satisfying and I'll be getting out again soon.
Thanks.
Al Kaplan, thanks also for the good advice.
Bill, before Star Wars invaded the imagination of some prop makers at some movie studio a lot of older camera shops would have "Junk Boxes" containing old Graflex side mounted flash units. The standard battery case took held a stack of 3 0r 4 D batteries, the end held a standard Edison base flash bulb, and the reflectors came in several sizes and were removeable. These battery cases were what became the basis for light sabers.
The side of the battery case had places to plug in cords and a little push button switch where your thumb would be if you were holding you camera by the battery case. A lot of photographers still had lenses mounted in shutters that weren't synched for flash, but wanted to use flash. SO! You'd take your lens to your camera repair guy, and when he mounted it on your camera's lensboard he'd also mount a solenoid on the lensboard connected to the shutter's release lever.
If everything was rigged correctly you could push that button on the battery case sending electricity to the solenoid, which would trip the shutter. Another cord between shutter and battery case would fire the flash bulb. External synchronizers were also available that would be actuated by the return path of the shutter cocking lever.
The big Edison based bulbs, as well as the smaller bayonet based bulbs, came in three synch varieties: Type F bulbs (fast synch) had a lot of the primer as a light source, but no metal foil. They weren't as bright, but the pulse of light would stop action fairly well. M synch bulbs used magnesium foil or fine wire wool in an oxygen filled bulb took about 1/30 of a second to reach maximum light intensity then gradually fade. FP (for "focal plane") bulbs were "long peak" and could maintain pretty much the same intensity as the slit in a focal plane shutter moved across the film.
As for brightness, those big Edison based could really put out the light, not a bad thing when film was maybe ISO 10. Back in the mid sixties my boss and I must have strung up a couple hundred yards of of ordinary electric light cord in the old Miami Beach Auditorium to fire a couple of Press 40 bulbs, in addition to the one on the camera. We were shooting from the balcony with a 65mm f/8 Super Angulon on a 4x5 camera and could stop down to f/11 with ISO 50 Ektacolor Negative. We made only three exposures because each time we took a picture we had to walk to the other end of the auditorium and climb a tall ladder to change each bulb. Those big bulbs were about a dollar each forty years ago!
As for painting with light, yes I guess it was possible, but the useful light duration of an FP edison base bulb was only about 1/8 of a second.
Sounds good! I just finished my first attempt with 6 sheets in the Combi-plan tank. Note to self: take more time to be sure that each sheet is in it's own slot. I lost a neg because it was sandwiched up against another sheet, and only half the sheet got developed. But those big negs (the survivors!) sure look good. 🙂

Thanks for the info Al - and by the way, do you know the push button on top of the lens is for? It is mounted right by the flash studs.
That's probably the button to lock the shutter open. Cock the shutter, then press and hold that button while you release the shutter. The shutter should stay open, so you can view the image on the ground glass. Set the aperture wide open for ground-glass viewing. To close the shutter, re-cock it.
I don't know if I'm just fooling myself because I know you've posted 4x5 shots, but I think I can see a positive difference in fine detail on my computer screen. 4x5 rocks!
