Thanks Shipmates
This has been one of those infuriating projects that appeared easy to start with; thinking, I only have to modify my original drawing!! But there is so very little info on this intriguing ship, that I'm still not sure if I've quite got it right. And thanks BH for the link, one I've seen but hadn't thought to include. On equestion does intrigue me; that is, if Russian's went for big hull-mounted sonars, why not the same in the Western navies? Though it is Saturday night and I'm a bit mellow
