TFLA 3000 on the B pillar refers to the original standard Austrian fire service designation, translating as "All wheel drive water tender, 3000 liter tank". It was built by Seiwald, a very long established Austrian body building firm, which expanded into building fire trucks around thirty years ago...
The previous owners were the volunteer fire company at Embach, in Austria, whose crest is still on the front door.
This company now has a more modern MAN WT on its website. Their fire station also houses a Mercedes Vario compact pumper and a Ford Transit personnel squad van. It seems rather well equipped for a village with only 1,500 inhabitants!
