can you take a piece of wire and see if the openings at the ends of the round HP valve chest (1) are linked to the ones at the ends of the LP chest. (2)

If they are linked then that is how the exhaust steam from the HP cylinder gets to the LP chest via cored in passages around the side of the LP chest. It's a bit of a long route but would have acted as a bit of a reciever.

I also wonder if the two valve rods are original as they are just plain rods so no means to adjust the valves by nuts. Maybe a previous owner started working on the engihe and only got so far. Or did someone take it apart and start restoring it, making new valve rods but did not finish them.
