Short Shaft Slip Yoke 727's in Old Airport Tugs?

I've never seen a short one with a slip yoke, but that means nothing, since I know I've seen a tiny fraction compared to some of these guys on here. Have you ever seen one? I've seen two styles of shorty 727s. One with the parking brake drum and the bolt on yoke and one without the parking brake drum and the bolt on yoke, but I've not seen a shorty with a slip yoke.
in my travels i've seen a handful out in the wild. eons ago i bought a 74 W200 with a 440 that had a shorty w/ a slip yoke and a divorced NP205. the 440 and NP205 were absolutely how it left the factory, but i can't say with 100% certainty that the shorty 727 was there from the start, although it looked to be unmolested to my eye.

besides that one the others i saw were a shorty box van/ice cream truck (P200?) and late 70's van chassis motorhomes with small blocks. any of the others were loosies in parts lots/swap meets, etc.

the flange mount style is the much, much more common variety-- both with and without the p brake. i know around here the 4wd guys covet those shorty slip units (along with 46/47RH) so they don't come up often.
