This set is meant to fill the engine compartment of the Hasegawa Sd.Kfz.234 series (not only the Puma as the label might make you believe). It contains 21 pieces in tan polyurethane resin. All pieces are cleanly cast without any blemishes or flash. The only preparatory work will involve the removal of the molding "carrots".

Some assembly of the parts is required, and the engine hatches on the Hasegawa kit need to be carved away and replaced by resin ones. All this is explained in the small manual. A painting guide is also given.
The set will greatly enhance the engine compartment, but some extra wiring and tubing will be needed to give it a fully authentic look. Some of this is mentioned in the manual.

The adventurous modeler might want to open up the engine louvres as well, to give the engine some extra exposure.

Note: I can't personally confirm, but I have heard that earlier releases had PE engine doors.
