This was a one off. They have never done a engineer with this last. Lumberjack laced boot resembled a viberg 310. Took 2 weeks of messaging before they accepted. Had to send in my exact measurements that I've sent to indonesian makers to convince them to try. Told them I will take full ownership if there's any issues. Once they saw my Instagram and that I do collect boots they accepted. They tried and succeeded. Viberg 310 engineer has finally been checked off my list. So far.
