Ahoy Robert!
Welcome aboard Armorama!
Your U-boot looks very good for a first timer!
You have done a good work, and if you still are to it, you can still improve it with just two little things:
- Paint the limber holes that were painted gray in black, from what I can see from your pics are not that many

- The periscopes should be painted steel color, near the housing and grey on top

You have made a good job and should be proud of it!
As Steve Joyce (Blaster76) so well mentioned, if you want to have more fun with this wonderfull group, we are just a couple of weeks to start another great Campaign - Give it a thought

Once again Welcome and Congrats on your U-boot
Skipper
