pilot light issues with 100yr old boiler?

Dont ask how, but my gas main got shut off... I have to relight every pilot light in the house to get the radiators running again because its cold! I have turned the main back on, and managed to relight everything except my 100yr old boiler. It has an instruction plate telling me to turn on the pilot valve. Hence the problem, there is nothing there that appears to be turnable, nothing stating pilot...I have racked my brain for hours. Any ideas? An websites I should check out? It is a large silver cylindrical boiler with a metal box attached at the bottom. The emblem on the box says burnomatic, it has a newer looking honeywell thermometor on the top. I have taken the metal box off the top and searched all componets inside.
