Update! Finally got around to doing some more work.
Bent the track holders into shape, fixed them to the tank using superglue:
Painted them, applied some weathering, hung spare track links and C-hooks on them, which I glued into place:
Why hang the C-hooks on the track holder brackets? Well, why not? I'm sure they used those brackets for whatever they needed to back in the day.
I had some tiny chain that I cut into 12 pieces of about 4 cm ish long, got a 0.5mm stainless steel wire:
Painstakingly scratch built retainer pins by snipping a piece of steel wire, bending it into shape, hooking it into one end of a tiny chain:
Fiddliest thing I've ever done for a 1/16th scale model. Almost as fiddly as the 1/72 Nashorn I'm working on, on the side.
All 12 done. Phew. Now to prepare the spots to attach them to and carefully superglue them into place. I'm hoping superglue will suffice. Then to touch up their attachment, and presto:
Working retainer pins. The jerry cans are held only by the brackets and pins, and can be removed.
Ok, that's the JP itself done. Now to add some stowage. I can probably get that done within a few days at most.
I might even consider submitting this to TotM for February. Do y'all think it's worth submitting among such great machines as others are building?
