Looking good with the B17. I did the same model a while back, if theres any interest for you have a look at the link scrowl down the page a bit and theres a few pages of the build.....
Thanks but, don't know what your talking about. I put all the ones in that are suppose to be put in before assembly. These two windows fell out of the already sealed B-17 when it fell off the bench. Fitting issues caused me to open her so I got to put the windows in, refit her, and now is back to where she was before the fitting issue.
