Hi Adrian,
I have been assured by folk at the Technical Dept., at RNLI Poole, and by two Engineers / Mechanics likewise, that there are no differences - they are all from the same moulds. But then Mk1 [John] brought to my attention that there are in the fixtures and fittings - with photos to prove. I think that in their [RNLI] 'eyes' this is the case - but some of us as modellers, keen for accurate detail, spot items to disprove this. I know quite a lot of modellers that have now bought this model and are following my build and I am just pointing out that the research and plans used need to be from a known source and the 'provenance' and 'scaling up' size known. I know one person who scaled up to make it 13 metres [whereas it is 13.6 metres], someone else to 13.5 metres and another to 13.64 metres. I have bought and 'inherited' three sets of plans and as I have pointed out earlier that on one set the nose of the wheelhouse is 150mm, another 147mm and another 145mm [the set that I am now using as the hull, deck and wheelhouse seem to correspond, give or take the odd 1mm]. For me it's the final symbiosis where windows line up with stanchions, that line up with intake / air conditioning valves and outlets, with 'eye-lines' drawn to aerials etc.,. It is at this point that I am 'adding my touches' to go along with those plans finally 'ticked' and being used. Some of my friends and acquaintances that have bought this model at recent shows and Club meetings have said they are not worried about this sort of detail and are just building 'as found' - some not even from plans - each to their own approach. As you well know, that if you are having plans enlarged to the size to work from [1/12th] are they to one, two or three decimal places and how accurate are the ones purchased from the RNLI, where quite often they bear the phrase 'do not use to scale'. Enough from me - you've all got better things to do - but I just want to make some aware that detail can differ. Hence my regular visits to Dungeness to measure the actual vessel, like others, I am fortunate in this respect.
