Remington Rider repeater

[oldiron]

The centre gun is a Remington Rider Tube-fed repeater. It takes .32 rimfire EXTRA SHORTS. Anyone know how short that is? I'd shorten some regular .32 RF. I think it's a 5 shot.
The other two are just fillers. A Moores 41 RF derringer, and a Williamsons
front loading 30 cal teat-fire. Thanks for now....

I believe the extra shorts have a case length of .390

I have wanted one of those little Remington repeaters myself do they have
antique status with the tube feed magazine?

Thanks rg. The Rem. Riders are antique being .32 RF, and built from 1871-1888. This one came from US without a letter.
