In the dim dark past, I built the old tool Airfix Swordfish and also the FROG one. This is an inbox review as I won't be building this until modelling supplies are designated essential supplies. It comes with two options for payload (bombs or torpedoes) , configuration (wings folded or not), colour schemes (camo or silver overall) and markings. The tooling is really nice and I love that a trolley is provided got the torpedo. The interior is very detailed. Things I didn't like were the lack of rigging diagrams, and the absence of colour callouts for detail parts (the only defined/named colours are those for the exterior.
All in all very nice and looking forward to building it.
