Doors – What kind of lock set do I need for this door

doors

I need to install a door knob and latch on this old interior door (the cuts in the door were there when I bought the house, and the original hardware is long gone):

Could someone please tell me what kind of lock set I need, and whether I should be able to buy it off-the-shelf? I can't find any in my box store that fit.

I think it might be called a mortise lock, but the only locks of that type that I can find are too big for the opening on the side of the door.

If you really need to do it, stop screwing about and drill the door for a standard modern lockset. You should be able to purchase the hardware and the lock/latch set at any decent window & door shop. They will lend/rent a jig to make it a simple job.
