This subject revolves around what publication a forumer should believe. An original copy of The Equipment Regulations or a self publication by an enthusiast. I am as open minded as the next bloke

The 1900 to 1944 equipment regulations, which I've just borrowed from the technical library, which I am holding in my grubby little mitts, appendix 52, list 1 on page 548 to 570 states quite clearly what the regimental markings will be. And DT is not Dorset. There have been a couple of 'cross-overs, such as SHROP and SALOP for Shropshire but nothing like this applies to Dorset.

If it makes anyone feel better without upsetting the apple cart, then I'll say that it IS Dorset. It's not of course, but like I say, that's what the good, but very old book says.

What's ironic is that where I've quoted this and similar books before, no ones batted an eye lid

So Dorset it is then..............
