Hi Stephen, back again!
I was looking at Stona's pictures and wondered if it might be possible to scratch build a beaching trolley which would enable you to create almost any sort of dio. Then I wondered if anyone made one as a kit so I checked on Google and found this:
1/32 Carriage for Arado Ar 196 (REV)
Gern
PS Just checking. You signed yourself off as 'Steven' on your last post, but you used 'Stephen' for your log-in. Which one do you want, or doesn't it matter?
PPS Just zoomed in on the instructions shown on that web page. Although I'd seriously struggle, I reckon anyone with good modelling skills could build one of those from scratch.
