6-piece mourning dress set for summer and winter

Tailored about 30 years ago at a local kimono shop, but never worn.
The basting stitches are still attached.
The crest is Sagarifuji (Wisteria).
My name is written on the hem of the kimono. There is also a mark indicating the dyeing method, which reads (Kodai Doro...) though it's difficult to read clearly (see photo 14).
This is a 6-piece set including a mourning kimono, obi, and juban (under-kimono), with both summer and winter versions for the obi and juban.
It was tailored for someone 170cm tall, so it might be a bit large (equivalent to a women's L size in Western clothing).
Length (measured while folded, from shoulder): approx. 172cm. Sleeve length (裄): approx. 69cm to 70cm. As the basting stitches are attached, I could not unfold it to measure the front and back widths.
Although never used, it is quite old. There are about two small stains on the winter juban, and the erinuki (neck support) has discolored (please check photo 12).
The kimono itself appears to be free of any visible stains or dirt within the visible area.
Please consider this understanding the condition.

Comes in a Bisho cardboard box (95cm x 38cm x 8.5cm).
I would be happy if someone could make use of it.
Please refrain from complaints or returns after purchase.
If you have any preferences for delivery date or time, please let me know when you purchase.
Thank you.
