1:144 aircraft photo-etch does what no styrene part manages at this size: FuG 200 and FuG 220 radar arrays, fine cockpit detail and fragile airframe fittings. Sets are drawn for named types, from the P-51D Mustang through the Ju 87 Stuka to the Bf 109, so a cabinet miniature will stand up to a loupe rather than hide from one.
Etch at 1:144 needs calm, good light and the tip of a pair of tweezers. Matching kits are in 1:144 aircraft model kits, the whole etch range across sizes in aircraft photo-etch sets, and the armament of a miniature is completed by 1:144 turned metal barrels. Fit radar arrays as the very last step and keep the model covered until then, because one touch bends them.
