Another new to me manufacturer Sabre, as seen here...

Hmmm... Seems that their G10 was a copy of LZ Models:

I hope they have developed their own kit this time.

An now we need a company to bring out a decend and "based on the mass production version" BR50 or BR52 in polystyrene. Preferably buildable as one or two of the post WW2 versions as well. With that railtraffic until the 1970s could be covered.

Oh and the BR52 please with the "Wanne" and not with a standard "Steifrahmen" Tender.

I'd rather have the Kondensator. I've got it in HO - have thought about scaling it up.

That tender is as rare as a honest politician. There where a maximum of 177 BR52s in that konfiguration build (Nr 1850-2027). Compared to > 6000 in total. As an alternative tender/extra kit - sure why not.

But the beauty of the "Einheits-Ackergaul" is that some engines are still in daily operations in a coal mine near Tusla and where active in eastern europe till the 80s/90s. And the UdSSR kept 3-digit numbers of standard gauge 52s in reserve to use in case of WWIII. So even a "Red Storm/Team Yankee" Scenario with the stumpy little wide assed lady is not out of question.

Not to mention that, IF someone builds passenger cars, non military scenarios are doable since 52s are extemly common operational steam engines in museum service (I rode with three different ones in the last 12 month). Some museums like the (recommended) VSM in Beekbergen have more than one "runner" and use them.

Sometimes the engine is the only thing that seems to like the weather:

And that's the beauty of it for me. I find the rarely seen infinitely more interesting. Although one could argue they weren't that rare during the war. They were FOR the war in large part - harder to spot, went farther without having to stop for water, and were actually more fuel efficient as well.

Post war is another matter. My HO layout (If I ever start it) is going to be the DDR circa 1980. Most of my locomotives are PIKO, as is ALL of my rolling stock. Several BR 52s of all types will be featured.
