@Don McErlean the art on that box reminds me of an English construction set available about the same time and right up until the 60's the Bayko Construction sets
Although they were a different method of constrction , many UK train modellers used them . They were a bit like Lego but instead of interlocking pieces the bases had holes in the into which rods were inserted and the pieces all had holes which then slid onto the vertical rods , much like building a besser or breeze block wall in real life
While I might find obscure things ( or in effect not limit myself to one country or continent) embracing all manufacturers of clockwork @Arne or Frenchy @FRENCHTRAINS always trump me in finding hard to find stuff in really good condition. I am like the junkyard dog picking at the scraps comparatively LOL!!!
Ottmar Beckh is the firm who bought out Adolph Schuhmann ( thanks to the Nazi Party yet again ) in 1939 and continued trading til 1973 ... they did Ogauge directly after the war but managed to semi succesfully board the HO train craze later with mainly battery powered sets in the 1960's
My Dutch friend has decided to let me have the ADRIA consist as well as the Spring drive railcar so kindly identified by @Arne via @sncf231e that we bought the other week , so some more rarities head south ... Again not great quality , but find me better ones LOL!
So this brings the ADRIA collection to in total one loco, 2 tenders and FOUR carriages
the "new " ones
