Firstly, Well done Ashley for the skimmer caravan, looks great, good article.
Re the above probs, did no-one read my article on making scale figures in Model Boats Winter Special 2015. which included a centre spread pull-out showing you all the sizes and scales?…..doesn't seem like it anyway…sob sob.!!!
Re estimating scale, measure the wheelhouse door or something like that, most people have to get their head under the door frame , this can be a rough guide to the height of a scale figure. Once we know the rough height we can guage the scale and then tell you if there are any available to buy or if you have to make them yourself.
Cheers……….Ron.
