Thanks for the compliment and suggestion David @davids_models, first I will try to build this sub and get it look nicely, later on I might add some crew.
@fiveten, @gblair, thanks for your kind words.

After a nearly two weeks holiday I started working on the sub again.
Baseplate was painted and coated. On the sub I added the propellors and the railing on the conning tower.

Next up will be mounting the guns and periscope.

Looking good, John.

@fiveten, @j-healy, thanks for your kind words.

@gblair, thank you George, our holiday was in the northwest of the Netherlands, a 2 hour drive up north from my hometown. We rented a small house, it was litterily called 'tiny house'. Sufficient for three persons if you didn't stay there all day. We spent most of the days sightseeing, by boat or bicycle or walking, this region of the Netherlands which is 3 meters below sea level on average. Impressive to see how they removed all the water in the 16th century using windmills.

Moving fast, my friend @johnb!
May I assume the finish line being not that far away?

@fiveten, @gblair, holiday break did indeed help to get some fast progress.

This week I was able to make even more progress. Don't ask me were I did find free time, I have no idea, maybe I'm modelling more efficient.
All parts are attached to the Uboat know, antenna wires, anchor, flagpole included.
Decals, although not that many, are applied as well. They did came on nicely. Most difficult decal was the flag, the was one part and had to be folded around the pole.

Started to work on the weathering now.
Following picture shows the right frontside without weathering and the second picture is the left frontside with weathering. Did try to add corrosion effects as well.

This sub looks fantastic, my friend @johnb! It's really nice to see it coming together.
Along with improved skills, surely you become more efficient model after model, this is pretty obvious.
Love the weathering, it really brings this model to life.
Looking forward to this super build!

@gblair, @fiveten, @davids_models, thanks for all the kind words.
David, your tips are very welcome, I did coat the flag after finishing the build, let's see how long the decal lasts.
