Thanks guys!
the model is pretty small: 11.5 inches (little bit over 29 cm).
It was painted with Humbrol enamels, weathering done with Citadel washes (designed originally for Wargamer figures, but I strongly recommend) and Tamiya Weathering set B.
The rigging is fishing line and the insulators painted blobs of superglue.
Overall, for $17 I've had a lot of fun with it.
It's a nice addition to my 1/144 collection of u-boats (the plan is to have all major types, with the exception of Type IX, which nobody makes yet...)
