Plusmodel is located in the Czech Republic and when you visit the company website you are given the option of an English language version. The links above go to that option.
To get some idea as to what products are offered by plusmodel, select the Catalogue option on the home page. The Catalogue lists hundreds of items that can be used as stand-alone models or items, such as the Ladder being reviewed, to enhance a model. My modeling experience with plusmodel products includes only a dozen or so of the aftermarket-type items, and I have been pleased with each of those items.
