Too many things going on to bother listing them.

Re: 3/4" pumps Van brocklin
I can`t see why U can`t see the valve rods and connecting arms from the front.This pump is mounted backwards no matter which way U look @ it.

Re: 3/4" pumps Van brocklin
The valve rods are pretty much blocked visually by the piston rods and cylinder spacers. You can sort of see them, but, they can be seen better if you put them on the side toward you. To me, the "back" of the pump is more interesting visually than the front". Not only can you see the actuating arms and valve rods, all of the steam chest fasteners and check valve hardware is visible.
There really is no backward or forward to this pump. It can be fit to a loco in many ways, none are more "backward" or "forward" than another.
Here's the "front" of the pump Here's the "back"

Re: 3/4" pumps Van brocklin
I even have a loco with one laying flat under the cab floorboard looking like a 'stoker' engine.
Yes, I had to redesign the check valves to work in that arrangement.
I have also found that using a socket head CAP SCREW instead of a socket set screw makes it easier to get things locked down so that they don't come loose..yes, they are a bit more 'un-scale-like'...but...our hands and tool are not 1/16 scale either..
