[TR] TR4 / 4A Commission Number Plates -- LBS or KILOS?

[Geo Hahn]

I'm interested in what late TR4s and 4As with ORIGINAL commission
number plates show as the unit of weight -- i.e. is the weight (which
may have been left blank) expressed in LBS or KILOS?

I know what Piggot shows, I also think I know what Moss and TRF supply
-- just looking for original examples to see if this was changed at
some point, or based on destination (home market, USA, etc) or just a
mixed bag.  Thanks!
