DETAIL: The remarkable detail of the engines - every last push-rod and cylinder cooling fin was created by hand.
For Napier master modeller and aviation enthusiast Ton Fontein next month will be a time to say goodbye to two old friends.
Two old friends with wings. Two old friends he spent many long hours, days, weeks, months and even years creating.
But he has no regrets as they will be going on display for other aviation enthusiasts to gaze upon in admiration.
They will add to the list of aircraft he has both built and donated to museums, here and in his former homeland of Holland. "I'm not too attached to them. And I need to make more room in the garage," he said with a smile.
His latest creation, and one of the two aircraft he will be taking down to the Omaka Aviation Heritage Centre in Blenheim, took just on two years to finish but he doesn't think about the hours involved.
It is part of a history of iconic propeller-driven aircraft he finds fascinating and worthy of being recreated in detailed one-sixteenth scale.
It is a stunning red Junkers 52 which the German company built and named after one at that country's aviation combat heroes - Manfred von Richthofen.
Like the "Red Baron's" Fokker tri-plane, it was painted red and bears his name.
Mr Fontein said he wanted to re-create the aircraft which had been designed as an airliner before WWII but which was quickly pressed into service as a carrier of para-troopers.
The one he has created is the airliner version, not the military version - the latter he said carried too many of the wrong memories as it was used to invade his old homeland.
"My son is a pilot now and he lives in Germany - he sent a couple of great books to me about the Junkers with lots of factory drawings."
His son also visited eight museums across Germany where there are Junkers 52s on display and took close-up shots of every part.
Mr Fontein, a retired consultant engineer, said researching every last correct detail of an historic aircraft was half the enjoyment of making a model.
It harks back to his engineering career - details, more details and getting it absolutely right.
It was the same as when he was building his previous impeccably-detailed model of Charles Kingsford-Smith's Southern Cross Fokker F VII 3m.
He drew on all the literature he could and was delighted to come across a mention of "konigs blau" - the blue colour used on the original.
He eventually tracked down a colour chart from an upholstery painting company in Slovakia which still used a hue called konigs blau - and it was spot on.
He sourced their colour chart and had a Napier paint firm re-create it.
"I got it," he said.
He turned each and every last 27 cylinders for the three engines on his lathe and used severed pin-heads for every last accurately placed fuselage rivet.
For the Junkers, which had a corrugated fuselage for strength, he said he "fluked it" after discovering that finely corrugated cardboard he came across used for parcels suited the 1/16th scale perfectly.
Every internal piece of framework was intricately cut and created, and he used about 800 pin-heads as rivets to close off the corrugations where they met the smoother parts of the fuselage.
When he saw that the Omaka centre had a diorama display of von Richthofen's downed tri-plane he got in touch as he could see the link to his aircraft.
"Oh they really wanted it so they are going to get it."
When he mentioned the Fokker they expressed interest in it as well.
So they'll both be heading south.
Another of Mr Fontein's recreations is also likely to be heading south in the future.
It is a WWII Lancaster bomber he built several years ago and Sir Peter Jackson, who is planning to re-make The Dambusters, has been in touch.
