Following a brief interlude with my thoughts on a 77xxx I returned to the Duke yeterday whilst recovering from a nasty bout of Bejing Belly (don't ask)

So deflectors are now modified to the single continuous handrail which involved unsoldering the small lower handrail and the handrail knob from the end of the top handrail. This was re-sited higher up in a new hole, two holes were filled with solder and then a new section of handrail soldered in with the join within the old knob.

Pic below shows the old one on the left, new correct (ish) one on the right

I've also fitted the PH Designs cam box covers, filing down the Golden Arrow resin to basically a rectangular lump and supergluing the etch over the top. Looked okay, but when I fitted the block back to the loco I need to remove more resin to get the top of the cover closer to the running plate. an issue possibly with over width Hornby cylinders?

Anyway, simple enough to pop the cover off and file a flat on the top edge of the casting - I will return
