Another single shot rifle?

I already happily own 2 H&R Handi-Rifles, a Sportster model in 17HMR andd a fancy Ultra Varmit Fluted model in .223. They are both terrifically fun to shoot and they are prized members of my locker. The other day I wandered into my favorite pawn shop and they had another one on the rack, this one had wood furniture, a cheap scope and a really big hole in the muzzle. It was chambered in 38-55!

Now what possible reason would there be for me to own a single shot rifle chambered in a caliber with roots that date back to the 1870s, that was intended to be filled with black powder and that shoots 255 grain pumpkins downrange? I really can't think of a good reason but that didn't keep me from seriously considering adding to the others in the locker. I haven't yet- but I'm thinking about it...
