Thanks for the info, guys! Much appreciated!
@Fatman the top of the tender certainly matches the Hornby style you posted- great pics by the way! Thanks for sharing! That last one looks like it’d go well with the Majorie & Auroa(?) Passenger cars
Regarding the tender- first, here are some more pictures as I did just notice that the top was screwed to the base in 2 equidistant pairings. @beardog49 might be on to something. I don’t have Hornby tender, to my knowledge, so I have none to compare it to:
I searched Hornby and MML and the most relevant things that came up were: Midland Mainline was a rail operator in the U.K.which operated from 1996-2007, Midland Main Line- a major rail line whitch started construction in the 1830s and goes from London to The Northern UK, than a 3 post discussion from 2011 asking about Hornby’s Midland Mainline coaches.
