Master-Model provides modelers with exquisite miniature turned metal parts that can be used in place of kit parts to add extra detail to models. Their sets generally are available for builders in all popular scales. This set (AM-48-096) provides parts to assemble crisply detailed 1:48 scale Hispano 20mm cannon in long fairings for the Fairey Firefly.
The parts are designed to replace the injection molded ones in Special Hobby kits without significant surgery. The kits have holes on the wings’ leading edge to install injection molded parts so it is likely the Master-Model barrels will literally drop in place instead. (Although the size of the holes may need to be increased to 1.5mm diameter to accept the plug on the end of the fairings).
