Thanks

, I have added a Sperrbrecher on a trip to Penang. I did forget to make that early 42 so it will likely find an unfriendly welcome in 1941!
What I noticed is this defaults to Unit#1 and then replaces unit #1 in the SCR when merged.
I will do another and take note of the last unit number in the SCR and try and make it that number. If not I simply take that one from the original SCR and put it on the bottom.
It is just for fun as German items are just not seen to any real effect by player. I might try a RND.mis but do not want to get too into this and make it work!
This does help better understand how things work.
