OK, I think we have the answer to those numbers on the back of the badge! I thought that they might have been numbers related to the League but then thought it possible that it might be a service number...and it WAS.

Attached are two snips that match the numbers from the back of the badge and they are 27th Btn.

I've not had a look in detail but it would appear that they are not related but may come from the same region.

It still suggests a level of hitherto unrecognised organisation as these numbers could only have been added to the bars prior to enameling as the process does not take kindly to impacts of any kind from the reverse.

I have examples to prove this!

As a footnote, see if the 10th Btn bar that started this thread is also numbered, although this may not have been a universal practice.
