I have two specific questions about particular features of older Record flat blade, quick-release wheel skewers.

First, the nut that secures the cam lever in position usually looks either nicely chromed, very black, faded black, or brass colored. It seems clear to me that the black is a coating (black oxide?), that can fade and slowly (or quickly, in the event of wrong cleaning technique) reveal the brass colored nut below. However, I don't know where the nicely chromed nuts come in. Are they newer or older than the black nuts, or are they perhaps one and the same thing ... as in the black is the top-most undercoating for the chrome? If they are different, does anyone have an idea of timeline?

Second, the housing for the cam usually has BREV. CAMP stamped on one side, with the first word stacked above the other, as follows:

BREV. CAMP

But I have a couple examples here where the words are linear, as follows:

BREV.CAMP

The linear type is found on all of the 1950s "open-C" skewers I have here, and it is found one ONE piece only on a set of 1960s "No-Record" hubs I have. All of my late 1960s to 1970s skewers have the stacked type. Therefore, I think the linear type is older, but I'm not absolutely sure, and I'd again like to know if there is a rough timeline. One possibility is that the linear type came with original Gran Sport era skewers, and the other type with the new Record hubs. Or, they could all be the same style of skewer, where the type change occurred, perhaps in the mid 1960s.

Does anyone know about any of these nuances, and/or can you all please check your confirmed original 1950s to early 1970s quick release skewers to compare? Thanks very much...
