Scorpion model (Bridge of Allan FK9)

Advertised for age 8+. My almost 8 year old grandson found it difficult and a 13 year old friend got as far as this half assembled version. It remains to be finished - or taken apart. There's a leaflet with information about Scorpions, Q&As, assembly instructions ( which I - Grannie- found difficult to follow) and the illustrated Anatomy of a Scorpion. There's a little stand to put it on when assembled. So I'd suggest someone older than 8+ - it's not LEGO. Box in pretty good condition.
