Already tried to write directly to them.
I used to be a pretty skilled model builder. Here's an example: 75 Turbo, Provence Moulage, extensively modified to have it looking like the real thing.
It proved to be one of my swang songs, maybe because stupidly enough I marked the hours spent on what's at the base a good 1/43 resin kit. At the end, the count summed up at something in the 120 hours range
Front end completely re-cast to have the front bumper at the right place, modified shape all over the model, all windows re-made from clear plastic sheets, internal detailing all from scratch, brake calipers in the wheels, name of the pilots out of 1mm tall Decadry transfers, etc... Pff...
