I haven't received it yet but got a shipping notice. I'll post my thoughts as soon as I get it. I see there are a few on Ebay still (I have no connection w/ sellers).
As I said, the hull halves on my SN are unuseable (they are both warped and twisted). This is due to low quality molds used (copper or zinc as opposed to Steel). From the pics I've seen, this isn't the case on the Alanger kit.
Length has been mentioned as a big
According to Planrolle Plan 8 (Vom Original P.81), "lange uber alles" overall length) for XXIII is 32.480m, or, 17.76" in length in 1/72. The SN kit is 18.75" long, or 1" too long according to the plans (if they are indeed accurate). I don't know what the length of the Alanger hull is, but if it's 1" longer than the SN kit, I will still have some surgery to do!!!
Interestingly, Hai/Hecht according to Vom is 36.13m, or in 1/72 scale, 19.75" (which would correspond to the Alanger kit if indeed it's an inch longer)!!!!
Looks like the Eduard set for the SN kit should work fine for both. I'll likely kit bash the two.
There have been some comments as to why there are resin parts in the SN kit that could have been done in styrene. The resin parts are quite a bit sharper than the plastic parts, and I'll likely use some of them (the top rear part of the CT for instance). I also have the Schatton periscope for the XXIII, which is awesome like all Robert's work)! I just ordered his mines and details for the VIID conversion:)
