 I might be able to help here:
c = Roman numeral for "100" and wt is of course weight.

 Some of us over 50 will remember interminably chanting the weight relationships at school. . . . Anyway cwt comes from here:
16oz ~ 1lb
14lb ~ 1st (stone)
2st ~ one quarter (28lb)
4qtr ~ 1cwt (112lb)
20cwt ~ 1ton (2240lb)
Up to our "metrication", commercial vehicles carried a large sign-written "plate" that defined the unladen and laden weights of the vehicle in tons, cwt, quarters and lbs; it needed to be large to get it all on!
For D-Day ship loading a similar format was used but only recorded the as-loaded vehicle weight and dimensions, a standard paint stencil was used with the various figures chalked-in.  You can sometimes see this in period photographs.
To this day we refer to people weight in stones as kg only conveys anything to the medicos.

 A fair bit over 3000lb, being 3360lb.
