NAS Fallon "Longhorns" HH-1N Iroquois (2)
The top picture shows the model as I built and photographed it back in 2007, on my kitchen table in the UK. The bottom picture shows the updated model on my kitchen table in the Netherlands.
This comparison shows a few of the updates. I think the original model was fairly accurate in terms of overall shape and proportions, and superficially the updated version looks very similar. However, I rebuilt about 40% of it during the upgrade.
