|Voyager series odds and ends|

Hello everyone, this is my first post here although I've been visiting the museum regularly for several years. I have a couple of observations and questions about the Voyager series of HP calcs, e.g. the 11C, 15C, 16C and 10C.
I own an old beat up HP-11C that has survived more than 20 years on 2 sets of batteries. It's been through the mill and even got run over once in the driveway (in deep snow) but it keeps on ticking. Recently the ON key started to act funny. All of a sudden it has to be pressed really hard to turn the calc on or off. Very strange that it started happening all at once. I checked around the net (and here) to see what it would take to fix the key for whatever problem it has. I decided against doing a self-repair job, and opted instead to buy a new one.
I did that on ye olde auction site this past summer. The calc I bought is nice and clean and works well, but I noticed a few differences between it and my own. For one, the battery compartment has a coil spring in it instead of 2 flat spring tabs. The second is the VDE logo (f in a circle) on the back near the battery compartment. The third is the color of the printing used on the front of the calculator.
Research here at the museum revealed that HP went to the coiled spring battery contact in later production runs of the 11C. Is that true for the entire Voyager series? Lately I've been seeing more and more on ye olde auction site with the f-in-a-circle logo on the back, and not just 11Cs. Does that logo automatically imply a coiled spring battery contact? Other reading has given me the impression that the coiled spring is less reliable than the flat spring contacts, and is prone to breaking off. Is that true?
As for the color of the printing on the front, the f-shift function labels are more orange than yellow, like on my old 11C. It's a darker shade and IMO more difficult to see, although it may just be a case of getting used to it.
Do those 3 things - battery contact spring, VDE logo, and face printing color - all go together? If I find a calculator with one of the 3 things (say on the auction site) is it reasonable to assume all 3 are present?
My other question involves the keys on my original 11C. Is it possible to get to the key contact sheet (for cleaning) without breaking any of the heat strakes? I still like my old calc better, missing logo, missing rubber feet, dented bezel and all, and if it's possible I want to try to fix the wonky ON key.
(Speaking of ye olde auction site, has anyone figured if the ripoff-artist not to be named uses a different ID for buying than he does for selling? I see him selling a lot more than buying.)
