Disassembling tender on Mountain Locomotive 4-8-2: NEED HELP

My dad needs help removing the tender shell from the frame. It’s a Mehano locomotive, made in Slovenia. He doesn’t see any screws or tabs and has no clue about how to get it apart. He’s hoping someone with one of them will know how to do it. There’s an electronic component inside that he needs to get to and there are wires sticking out from underneath that shouldn’t be.

Does anyone have experience with this locomotive?? Thanks in advance!~Liss

I’m not sure if all IHC Mehano tenders are made the same, but try unscrewing the silver-colored metal pin that the drawbar connects to at the front of the tender, and it should then open up.
