I must admit, the inspiration for this piece came from these two pieces, both Russian creations.
The first one would do 1:1 doubled, 2:1 doubled and SRT. It has an multiple intrinsic lockoffs. Mebbe it should be called the multi-lockoff Yakov.
Anyway, I think the Yakov is too big for our needs, but worthy of keeping on the shelf. Good design.
Another mini-bollard device is #2. I really like the guts on this one. Clearly, it is an SRT device, but if two of them were mated together, and an intrinsic lockoff configured into it, a design along this line has possibilites.
