Sorry for the delay Nigel / Andrew - I do not get notification emails & usually view the Forum without logging in so missed your postings.
Nigel, your photo does indeed show that the reverser is out of timing. The scribed line should be flush with the valve block face whilst in reverse so needs to be further in. Two ways to correct this, either
1. Move the reverser lever quadrant backwards. As you have radio control fitted that is going to work against us here so you would need to disconnect the servo linkage first. The reverser quadrant base has two elongated holes which allow for this fine adjustment, and is secured by hex head bolts or cross head screws.

Ideally if you have a spare M2 bolt or screw (if not use one of the mounting bolts/screws temporarily) use this to hold the reverser lever in the reverse position. Loosen the mounting bolts/screws and slide the quadrant backwards until the scribed line is flush with the valve face. Tighten the mounting bolts/screws. You will now need to adjust the servo linkage or reposition the servo horn so that the R/C is now holding this new reverse position (hold your transmitter control to reverse whilst doing this). Once adjusted you can remove the M2 bolt or screw from the reverser lever.
2. If there is not enough adjustment by moving the reverser quadrant, then you will need to move the piston on its threaded stud. Slacken the M2 locknut at the back of the piston reverser valve and rotate the piston clockwise to screw it into the required position. Tighten the M2 locknut.
Hopefully job done.
