    Yep, you've got a certain amount of liberty building this type of boat, no one was the same, i've opted for that floodhole ladder on the side of the conningtower and drilled some extra holes on top, matching the conningtower drawings inside that XXIII book, just to make it different.
    The lack of pictures doesn't enlighten our job on this boat, there must be a lot more pictures inside the archives of both the English and American navy, still highly classified offcourse, they must have sliced this boat in parts to learn as much as possible about the latest technology.

    Thank you Manfred, noted and will do on the hole! I saw that looking at pictures, so will add. Because there are so few photos of the XXIII and so many differences, you can put any number of things on and who is to say you are wrong?

    Ahhhhh, you're now a official member of the dark side, lovely details, a feast for my eyes, now you know why i always want to research a type of boat for a year, it will spare you the drawbacks when you discover new details.
    Spoken about details, at the back of your peroscope protector there has to be a round floodhole, that's what i've found on researching my pictures, a minor thing, but most usefull to get away those pesty airpockets.

    The oval opening is not a light. Michael posted "According to the drawing in VOZM it's a "Tauklüse", means hawse for ropes" . That is why you check your sources.
    so the decision is whether the periscope mounting or the unique light housing on the upper aft conning tower.

    Speaking of checking your sources, the drawings in the Bronco instructions are not accurate. I can not find a photo that shows the black waterline being used and found that ships use them, but u-boats never did. I guess it looks pretty.

    Alec, Thank you, I am glad these postings are of value and I appreciate your encouragement.
    Earlier I asked about a white light for navigation on the Type XXIII. I saw a model of a Type XXIII with it on the periscope and wanted proof the Type XXIII used it. A gentleman by the name ofMichael shared this photo, but said it was for a Type VIIc (U-281)

    That is cool, but then he also shared this one (U-2360):

    Bingo!
    I also read that the oval depicted on the Bronco model's sail (aft and bottom) was a housing for a light. I will try to find that source again.

    Tom I know I haven't commented much on your XXIII but I am really enjoying what you are doing plus I get a kick from the tips n tricks you've done to date.

    Began by melting the tip under a flame. I quickly saw that was not going to work. Then I used a thick CA to round out the tip, it seemed to catch the melted part and make a nice bulb. Then this morning I needed to dip it in the thin because of a bubble. O.K. slot machine handle set aside to dry.
    Installed railing and antenna base. Broke external railing (twice). I just know that these details I am doing might last a patrol or two, but probably not much more. Antennas will disappear, poles will break, but for one patrol it will look good.

    In that case it's just a matter of slicing off sections with a razor blade

    Sounds plausible, redboat219!!
    Good call!

    Scaling them to what you need may be a little problematic. But, the trial-and-error process
    would certainly give you some useable data!!

    Might have to try that just for fun!!

    If you used heat stretched styrene rods with hexagonal cross section you'll get bolt heads.

    Decided to go with colored glass versus colored bulb. So painted clear red and clear green on the light cover.

    Then I tried something silly. Could I drill a tiny hole on the edge of a plastic tube? then do it eight more times? and make them even?
    The short answer is yes, sorta, and no.
    I drilled .031" hole on the edge of the 5/16" plastic tube. id that eight time, but did not get them even. Stuck lengths of .030" rods in and glued them in.

    Let it set completely. Then trimmed the rods and sanded the bolts as well as thinned the base.
