I'm so impressed with my KTM built FEF-3. I always consider MG and USH locos to be pretty much basic brass models and a distant 2nd place to Korean built models. I knew they had drives that would outlast all of us, but I considered most of the casting details to be very crude....wrong.
For a model built back in the 60's or maybe the 70's, it's a real eye opener for me on fidelity and quality of castings. I've been gathering parts from many sources (PSC directly and KEY & OMI indirectly) and I can tell you these original 50-60 year old castings are superior to most of the Korean built parts I'm getting..........in both fidelity to scale and quality of the castings.
I never really looked at any of the USH FEF-3's I've owned over the years as they were just daily drivers. And I haven't looked at the smoke lifters that came with the model since packing it away in the late 90's, but checking them out just now I found a minor detail that blows me away.
Just like the prototype, these smoke lifters have a metal stiffener edge all the way around the perimeter of the sheet metal. Some poor Japanese artisan had to solder on this tiny, tiny edge and I just missed this feature. Also, the pressed rivets are just as impressive and are evenly done throughout the lifter....what a stellar job!
