Royal Albert Lavender Rose China set

I collected this set thinking I already had pieces of it at home, but I was wrong. I'd rather keep a more sentimental set than stock pile a new one. As far as I know, it was never used. I washed them when I received them as they were all still in original packaging. It's gorgeous and is all in amazing condition. It's also nearly a complete set. Hairline crack on the gravy boat and a chip on one of the other items (all images included of damage I know about) Missing the big platter for sure, not sure what else if there is anything else. If there is supposed to be a tea pot, I'm also missing that. I see these sets going for $400 for a few pieces to nearly $700 for a full set. Asking $450 OBO. This set is probably around 20 years old or more.
