Is that RO as in flat-top or Red Russian ? How many...lemmysee, thers Eeni, Meeny n` Mo. .. Hmmm just did a count and I think I might have fixation complex or similar. Total Might be seven but gets complicated when you consider the ones with alternate deck and superstructure ie; MacSpringer and Spruffy two tops sharing one hull. Same for HMS Sprub and the new Orca, sorry Porker. I dont count the unfinished stretched (doubled length) one and the King sized kit in the garage (a X4 sized manned version, yes I can squeeze intae it). So you see I`m not really a boat modeller more of a Springerite. The list is 1. Maid`o Irn, 2. MacSpringer/Spruffy, 3,Fireboat "Sprinkler", 4,Swedish stealth patrol boat "Stringer", 5, H M Coastguard vessel "Springberry", 6,Workboat/log wrangler "Wildcat" , 7.Sprub/Porker. Stretched is pending, it was going to be an aircraft carrier and big yin def a springtime project. Then there is the wandering adopted kid , the real RO , now wintering in Helsinki. Back to lums on Puffers, looking through The MacKenzies photos there seems to be a few with a slight ( 2degree ?) rake on the funnel, might be a photographic aberration of course.
