Hi,
I see that gold-snipper has listed a pile of old IBM unit-record and
DASD equipment on eBay. (The category is Vintage Computing Products
=> IBM.)
The prices are not low, but then again it is working stuff, not scrap.
Looks like he's got a 4381 and all the trimmings.

(I'm not him, and I don't collect mainframe equipment, so you probably
now know more about it than I do.)
