brad black wroteit went round with the round bodywork of the 92 bikes. i think the top one is tricolore, but then it has indicator mounts in the side. so maybe not.
i got a new one for my bike 10 or so years ago and it's the lower type. it looked the same as the chopped one i took off from memory, apart from the 2 holes in each side for the usa reflectors.
actually, it looks to me like the top one is a skillfully and unusually chopped lower one. unlike the usual "cut off the bottom with a wood saw".
I felt the side profile by hand and each side felt different one having a slight dip in the radius, so I suspect that you are right Brad as was Spike who phoned me...thankyou all for the input. That trimmed item is now of to a new home.
PS lambretter...some had holes for the US style safety reflecters, though I am not sure of those holes.
