This antipathy seems pretty much mutual, this was not always so. In fact there was a time when quite a few Londons officers were quite keen on the Idea of a single Guards Cap badge for the regiment, They tended to be the non deploying holders of the windy pair (QGJM, TD)or the Flatulent four (QGJM,QDJM,TD,VRSM).
At least one had an MBE and TELIC medal (and was very keen on his BRB appendages).
They all seemed to be very keen on cutting around in the Blue Red Blue Guards tie. That is until they were told in no uncertain terms to take them off. I hear the official reason was that they were wearing them at inappropriate times , or that the wrong colour was at the top of the knot (For this read “You are not the right sort”). After which they all re found the loyalty to their individual cap badges.
Really, when did that happen? Genuine question - as there certainly were a lot of BRB ties still being sported by all LONDONS ranks last time I looked (albeit a couple of years back). I'd also been told that the wearing of the tie by the LONDONs was at the specific direction of the senior colonel of the household division.
