Welcome cmwags and I, too, am sorry for your loss.
If you're looking to donate the kits, see if there's a local VA in your area. Some will happily take the kits to distribute. Same with your local VFW. I haven't donated yet but I think in the next month or two I'll be taking a trip down the road to my local VFW to see if they'd like some of my completed kits to either display or hand out.
I've also seen where people donate them to local Boy Scout troops. I think I remember another one who built some for their local high school history teachers. There are so many possibilities!
I hoped this has helped,
Eric
