When producing replicas, we always prioritize the quality and fidelity of the original before shortening the production time. We also try to preserve the originality of the technologies.

On the contrary, in cases where the original technology did not meet today's safety requirements (for example, brake shoes, brake pedals and footrests made of thin-walled bronze castings), we replace these parts with a faithful copy, usually steel - workpiece, weldment or their combinations.

A typical case is the replacement of moldings with a part hand-punched from sheet metal on temporary hooves. Few people master this method and it is quite time consuming. However, the production of parts using the original technology (ie using a single-purpose pressing tool) would be significantly more expensive with a small number of manufactured pieces.
