This model is a variant of the Liebherr R 938 by Conrad and is painted in the livery of the Swedish company Emtbjörks AB. However, Emtbjörk's real machine is a Liebherr R 930. This looks quite similar to the R 938 but has a smaller counterweight and a smaller engine with just 245 instead of 299 hp. Also the operating weight of the R 930 (30–36 metric tons / 66,000–80,000 lb) is lower than the operating weight of the R 938 (37–40 metric tons / 81,000–88,000 lb)

The model was initiated by the Italian model dealer Giftmodels.it in a limited series together with some special extra parts.
