How to light this type of basic, old fashioned gas-cylinder-powered gas oven? My rented apartment has an old rickety gas stove, fuelled by a hose connected to a gas cylinder. No electricity is used at all in any way. This is fine because in this part of West Africa we get constant electricity outages, but I can't figure out how to light the oven part.

Every guide I can find online assumes I'm trying to light a sophisticated gas cooker with a fancy feature like:


A pilot light, or some obvious recess to light first
A self-lighting spark when you push the oven dial
Some kind of electric indicator light or control system


This seems to have none of these things. It's basically just a tin box connected to a gas cylinder. 

I can smell a little gas after having the gas on for a while, but no amount of using a plastic lighter near the obvious holes inside the oven actually lights anything, and I can't see any clues as to where the gas is coming from. Obviously I don't want to mess around too much.

Brand is Westpoint, it looks like it might have been made in the 1960s or 1970s, no clue about model. Here's a photo:
Back when we had one of these, we used to turn on the gas, wait for a tiny while (I seem to remember 4-5 seconds), then drop a lit match into  the front center hole. That would light up the burners. I'd err on the side of too little gas until you're used to it, and it may take a few attempts 

Mom was pretty good at it, but that might have been through years of practice. 

This video goes through the whole process, though I could have sworn you didn't need to push down the knob
