"Bollards", I said as I scrabbled in the bottom of the box looking for the the final parts to complete the model. The trouble with a second-hand kit is that you can't be sure all the parts are present.
One missing piece was the front bollard - but that was easily replaced with a bit of plastic tube and a 4mm diameter disk made using the handy leather punch.
At the back, the winch was missing one end, easily replaced with a bit of Plastikard even if it doesn't have the rivet heads that should be there.
Tricker were a pair of capstans. If I had a lathe to hand, I'm sure replacements could be turned up. As it was I improvised with a couple of brass bushes supplied with the servo. I've never really understood why these are included, probably an aeromodeller thing, so it's nice to find a use for them. More plastic disks from the punch (I must buy a proper set) and once they are painted, no-one will notice.
