The object is explicitly a half-size model based on the published design, not an original medieval pump. The made field 1200–1210 is not used as a reconstruction manufacture date. Its approximate dimensions and 272 kg weight belong to the model, not an excavated original. Catalogue title/made/maker/details data are CC0; descriptive text CC BY 4.0.
