Just finished making up cardboard model of this K3 taken from an item published by our Dutch friends some time ago. Started during Covid, rediscovered and now complete but without mudguards and lamps -altogether too fiddly! length about 6 1/2". Doesn't look too bad but the wheels don't turn. Simon C.
A bit of fun anyway, and just think, if you scaled up the set of cut-out drawings to full size you could have them laser cut out of sheet steel/ally and make yourself a full size replica K3! Simon C.
