If you still need this information or were unable to locate it, the Transtar II & B21 targets are still currently used for the Navy Handgun Qualification Course. The Transtar II can be located at Speedwelltargets.com, entering "US Treasury" under the search field. The Blue 24x40 is what we currently use. This is a versatile target because, as per the 3591.1E S.A.M.I. Manual, it can also be used for our Handgun Practical Weapons Course, Fam-Fire and Sustainment shoots.
Please contact me if you have further questions.
