Not the most glamarous of models, I know :

Found a wreck of a towtruck in the thrift store today, 25 cents for it and some other things.
Some cutting to remove it from the wreck, some plasticcard, a base and some paint. Nothing fancy.
In 1/300 its a rather large radioantenna, in 20mm een radioantenna and in 28mm....also a radioantenna. Fits from 1900 to the future. As the top has a magnet in it, the tip is removable and can be replaced with a sattelite dish cluster or a crane or whatever I can think of.

Finished some 1/300 containers as well (left side pic)
Next to a 28mm fig (so sorry, 20mm pics failed)

Nice objective (aka something to blow up) and worthy addition to my bunker, as well as being really universal.
