Jeff - All of the windows in my '41 were in pretty bad shape; either cloudy or delaminated to the point at which the glue was visible. There were also some DA scratches in the glass from sometime in the distant pass.
Although it wasn't in my original plans I ended up renewing all of the glass because other than not being able to see too well out of it the condition distracted from the rest of the restoration.
Good luck,
Don
