Roland, thank you so much for your assistance!! I figured that the Tender was likely Hornby/Meccanno, But my search for the MML with Hornby, meccanno, And Hornby meccanno didn’t bear me any fruit. Will certainly be googling this Bub loco- thank you so much for your help! I really appreciate it!
Just a thought - not trying to be the spelling police, but if you spelled it "meccanno" (proper is meccano), it would miss a lot of search results.
