very nice.
I circled the caps I saw in red for the style I'm familiar with, the ones in yellow I'm not familiar with. I don't think I've seen caps with connections on either end before, not that I've seen a lot, but there's enough visible writing on the orange one anyway to tell. the silver ones may not be caps, but I think they probably are.
the one circled in blue... no idea what's going on there. looks like a adjustable cap? no idea if such a thing even exist.
