Hi mines - 24 years old now one of the matchbox types, built using that clear acetate strip that came with it and several tubes of model glue, ie glue the joint then apply glue over the top sandwiched between the hull and the acetate. has not fallen apart yet touch wood, brass prop 6-8" long has a decaperm 6V motor and i use two 'titan' 6v motors for ballast / power, never did like the guns so replaced the rear gun with a airfix bofor's (since reading the anatomy of a ship book by john roberts - a very good reference book for options/drawings by the way - they carried what ever was available / aquired), though not strictly to scale i use two 50mm browning machine guns from 1/35th scale tamiya jeeps.
In the early days she ran on a smaller motor run on 1.5v 'C' sized batteries - oh the follies of youth, didn't do to bad in a competition though. has sunk once in a local lodge, sunk by the weed wrapping round the prop and dragging her down, and has had several attempts to get the running gear to work properly without success (still needs sorting), she usually only runs for twenty minutes before giving up, good scale speed though.
Most of the body comes off to allow easy access (cause i am lazy and dont want to struggle getting things in and out). Properly ballasted she took 75mm (3") waves on the lodge and provided she stayed into the waves, did not take on much water, so quite a good starter boat for a bigginer.
Has been displayed at the ellesmere boat show some years ago when i was a member of the North West Model Boat Club, along with my 1/72 scale German 'S' boat which has much of the same problems (trouble with being a office jockey and little engineering/electronics experience).
At the same show i counted 47, yes 47 flower class corvettes one or two 1/48 scale and several whalecatcher/ earlier versions, but the majority were snowberry types.
