Yes, a lot of them did Jim, but their effectiveness was limited. Some sparks flew out anyway. Also, not all of them had the spark arresters.
I've been trying to find pictures on the net similar to the ones I've seen in John's books, but haven't located any yet, which is a shame because they are quite amazing.
John also thought of the possibility of static electricity, as mentioned here earlier by jonm and foolestroupe. I'll ask him some more about it tonight.
By the way, coal burns differently and doesn't make sparks, which is one reason why most steam locos ended up using coal.
