Master Model from Poland specializes in metal turned parts for aftermarket kits. In my personal option they are among the best in the market. I really like their products.
This set is devoted to the weapons of the Hawker Typhoon. There are two options for that kit in 1/48 scale: Hasegawa and Monogram. This set can be used with all of the above, with different modifications in each case.
For all the makers you are instructed to drill holes in the wings for the fairings and to replace the plastic parts with the metal ones. In the case of the Hasegawa model (see photo) it could be possible to modify the wing fairing and just use the cannon barrel. You’ll lose a bit of detail, but you “gain” less effort to modify the kit. You are also provided with a small photo-etch fret to dress up with wing area around the cannon fairing.
