If your Speed has two shutters, one at the lens and one in the body - called a rear curtain shutter (which it should have if of the vintage you say) you will need a cable that connects both to the flash - if of course you intend to use both. If not, just connect to the shutter you will use. On the side of the body behind the Kalart there should be two prongs like the two prongs (which you describe as terminals) on the lens shutter. These take a bipole plug like that used on shavers. You can in fact make a cable out of a shaver cord, or you can buy one from a place like www.paramountcords.com. The cool thing about Paramount is that you can select all the required tips and get a Y shaped cable that will connect to both bipole outlets on the camera (lens shutter and rear curtain shutter) will allow you to use a modern flash if you get the appropriate plug at the other end - pc or whatever. Or you can use it with the Graflite flash gun and some flash bulbs - just make sure the third plug is the one you need for the flash, which I think is called a household plug (right?)
If you have a solenoid on the front lens board, this requires a male bipole plug I think, but I could be wrong. I have removed mine and just use the bipole on the lens shutter with a modern flash. The solenoid, as I recall, is specifically for use with flash bulbs, but how and why I couldn't tell you precisely - has to do with firing speed and sync. Maybe. I think.
How I get any photos that are actually representational of something I can't tell you.
Someone else will have to help you on a source for flash bulbs, or you can check the Graflex pages, which while difficult to search through sometimes, generally contain everything Graflex - www.graflex.org. Or here on Photo.net.
Terrifically fun camera. Get a Polaroid 545 back and shoot a lot of Type 55 P/N film. Then when you run low on money, get a Combi-Plan tank and shoot your favorite black & white, develop and print in your bathroom. Buy a fedora. Smoke a cigar. Complain about the Roosevelt administration.
