Hi Dan,
I agree with your criticism of the 1:570 kit, I have built many over the years adding more detail as I learned more about the ship.
My final product I have sanded the solid bulwark railings down and used chopped up sewing needles and fishing line for the railings, I carved out the forecastle anchor and well, I used fishing line for rigging and I used the decal set for all the windows because I had painted them all on once and it takes too long. It looks like a museum quality model I must say.
Regarding your new box for the 1:570 Revell Titanic, curiosity provoked me to buy one to find the answer, and it is the same 30 year old kit inside a new box.
I am equally disappointed with the large scale Great Eastern model I have from Revell, it lacks tons of details like the incorrect paddle wheels and missing fifth funnel.
I got the 1:144 Missouri kit for a gift on my birthday and I was so displeased with the lack of effort and correct details that I ended up selling it on Ebay.
To add to Michael's comment, like everything now a days lack of historical concern and money seem to be what have brought even the best model makers down to sub standard levels recently, such as Revell.
Best Regards,
Brian
