4 military die cast warships

These 4 military warships are unique! Looking at them from right to left-- 4" warship with "K880" on side. The next one , on bottom has the following "MODIFIED BLACK SWAN CLASS LOOP (BRIT-PG) ,W.A. Framburg & Co., Chicago, 3" in length. The next two are basically the same length, 2 1/2" but one is green and the other is red. Both also are tootsie toys. All are in great condition except they show some usage.Buyer pays $3.50 postage, add $1.35 if insurance is needed.
