Congratulations on your anniversary here in the forum, Toshi! And great choice for your anniversary build! This is a great kit, yes, even if it is older, and may need some work. I have two in my stash, one for conversion to an LB-40 for General Tinker's airplane at the end of the Battle of Midway.
When I was a kid, I built the -J, twice, and I always wondered why they didn't do the -D first. I had read about Ploesti, and I wanted to build one of those Liberators. But the -D kit wasn't around, in our stores, so I never knew about it.
I will follow your build with interest!
Oh, and some kit trivia--Monogram engineered it so that you could remove the wings easily for transport. If you get a good pop, there's almost no seam, with the wings installed.
