Thank you Lorenzo. Who would think that the Shirase would be a character in "girls with hardware" anime. I search the anime and I was in awe at the majestic Shirase. Regarding the brise-glace some time ago (I can believe 3 years ago) I did a what if Canadian Ice Breaker. This French models would easily fit in the simples categories. But be aware that the cabin is not symmetrical and it is better to splice in half and use a mirror image.
PAPERMAU: 1966`s Marabout Junior Icebreaker - by Toto - Navio Quebra-Gelo
The what if is here:
What-If USCG vessel in 1/400
Regarding the Olli Bizer I have not seen it.
Thank you Herky: I totally forgot about the ice resistant Bear class!
But this is definitely not a simple model. 31 pages between model, instructions and diagrams!
Just the helicopter has 34 pieces, some of them in quadruplicate, 7 templates, and a few wire pieces!
