I appreciate the compliment Al. I failed to mention earlier that when I thought about converting my bookcase to pipe cabinet, my lady friend said to me, "your just now thinking about that, I thought a long time ago that you should use it for your pipes." I was shocked, to say the least. But I know I have a keeper.
I peruse the antique shops in my area about every month or so and I haven't come across another cabinet like it, but I know they are out there. It really is perfect and although I want to outgrow it, it keeps my TAD and PAD in check.
I hope one day you are able to find that "china/pipe" cabinet you've been looking for.
