Not bad for such a 40 YO model. I read that some of details are not accurate but what the heck it looks great when finished!
Of course it has his drawbacks, namely if compared with the newer S-100 from Revell, like many flimsy parts that will self destroy if used, specially, for Wargaming.
But overall a great kit, well detailed, with some excellent crew models and it really looks like the real thing.
The rigging is thin cord from a sewing kit.
Like many Airfix kits the underwater part is separate which allows the model to be portrayed in a wargames base.
As always everything is paintbrush. The base is a piece of balsa wood textured with silycone.
I may have rusted it too much wanting to portray an old Schnellboot (model S-7) on D-Day times.
