Calculator Security Base w/Lock

Just for thrills I ordered:
https://www.ebay.com/itm/384693224682
which has a multi-application title: ABUS Key Blank 24IB - 26- 28 - 41 KBR 5 Pin

Evidently it fits multiple things:
"Fits ABUS padlock models 24IB 60 & 70, 26 series, 28/70 and 41 series KD padlocks"
And described as: ABUS key blank 24RK/26 KBR 5-pin right handed

Whatever that all means, I don't know. I have no association with the seller, no commissions here!

But, for whatever its worth. This key does fit my classic cradle. Have no idea if all classic cradles use the same key type.

Has anyone recognized the NI/NNI key type or manufacturer of the key blank used in my Woodstock cradle?

thanks
