I have a couple of spare sets of Ilford,and also Kodak if my memory serves as correct, VC filters in my surplus gear in the garage attic. Some are in NIB shape.
I cannot recall if they are for below or above the lens use. Let me know by PM if you need VC filters.
I think I have a new spare bulb to suit that model as well, lurking in the back of a darkroom drawer. Keeping a spare bulb is good, and use it dedicated to RA-4 printing, if you go down that part with this rig.
