Wow. Was just offered one for my Madame Dixie, checked the price, saw this, had to update.

B/Os at 20.

Sale: sold for a DBD Stout Shako - 21 * 0.9 = 18.9 rounded up. B/Os at 20 keys.

Appears it sold alongside a Phos Heavy Duty Rag for a KAW Pencil Pusher.

(Making it 10~ keys). Outlier.

All other sales seem to be either too old, or have gone to private backpacks.

I also found a large trader buying from scammers from this, so "yay"?

Feedback appreciated of course.
