Hello Ned & Dodes and Russell,
thanks for you're input re these two boats ,i have found that the German Navy purchased two boats to the brave design but with enclosed bridges as Perkasa ,named Pfeil p6193 yard number 2544 and Strahl P6194 yard number 2545 these were the two boats handed over to the Greek Navy and discarded by them in 76 & 79. Swordsman and Borderer were bought by as Russell said Haydon-Baille. And now not wishing to drive you good peaple to suicide i'm consigning this can of worms to the deep.
Regards Mel
