Follow-up info, for those interested in details . . .

> I couldn't find any listings for HD-loaded shells in wartime ammunition catalogs. The earliest mention was in an October 51 catalog. It looks like it was a postwar munition.
> The CWS WW II history "green book" says that HD was a late war product for the US. The British may have been using a steam-distilled mustard before the war but the US standardized on the "cleaner", vacuum-distilled product as HD.

Just in case, as I do, anyone plans on doing a ROK 8 inch, these may come in handy. Also shows, in no particular order, 155 standard and base bleed projos. Unfortunately you can't see all of the markings, but in real life you never can either.

Also important to note in your dios - chemical and WP rounds should never be displayed lying on their "sides" i.e. horizontally.
