Not a lot. None seem to have been at Edinburgh sheds, nor at Carstairs. Geographically the closest would be Grangemouth, which had a couple. 44320 was there from at least 1950-61. However, I think it unlikely they would come from there down the ex-LNER main line. A few "ex-LMS" passenger services did come this way, from Stirling and turning off at Murrayfield into Princes Street station, but these were commonly Black 5 turns.
Motherwell ones, again just a few, might be more likely coming along the Shotts line, mostly pre-LMS ones, which were unusual in Scotland anyway. 43884 was there from 1950-61, while 43883 moved from Grangemouth to Motherwell during this time. By the end of 1962 there weren't any left in Scotland.
