Adross YOU are right in thinking that they are the same Boats as in David Metcalfe's plans as you can see in the following link No 85 and 96 are they same boat just no is different.The Nz Maritime link is interesting to say the least.I bet Hazegry never thought this would turn into such a reasearch marathon {-) {-) {-)
But We can safely say we got there in the end

It might be a bit of a marathon (aren't they called Snickers now?!), but if it provides some conclusive answers for current, and future modllers, it's got to be a good thing.
Actually, the links you provided have opened up a couple of new avenues of investigation, which answer some points, and creating a few more...
First, I must apologise as I can see that information I posted initially was misleading because I added the word 'Yarrow' in brackets ahead of the details of the plan. Having already picked up on the T.85 (or TB-85) designation from the Joe Lines illustration, and not for a moment considering that it may have been applied to more than one boat.
This factor is fairly obvious though, when following the rulebrittannia.pbworks.com (http://rulebritannia.pbworks.com/w/page/4577683/British%20Torpedo%20boats) link (image below). In fact, there are several other doubled-up of designation numbers,which is also worth being aware of, e.g. Two TB96's, with one being shown as a Yarrow, and the other one a White.

Which reminds me, I wasn't sure which link was supposed to take me to " see in the following link No 85 and 96 are they same boat just no (number) is different.", although I found a link to several museums in New Zealand Museums of Banks Peninsula (http://www.ccc.govt.nz/cityleisure/artsculture/museums.aspx), which also included a 'pdf-file' of a (partial) Vessel Plan (http://resources.ccc.govt.nz/files/TorpedoBoatPlan-artsculture.pdf) which might be of use to some people (err, Mr Hazegry, that'll be you :-)) ) - enjoy!
