Flyhawk has created sets of upgraded metal masts, with a small frets of photoetch, for 1/700 German ships. This set is for upgrading the 1/700 WW2 German capitol ship Gneisenau.

There is a small fret of photoetch to replace the platforms and yards that go on the masts. There are also 2 tapered brass rods 70mm long to provide material to replace and upgrade the actual masts. Modelers will need to be able to cut the brass rods to length.

There is one single-sided page of instructions. I like the use color as an aid to folding in the proper fashion.
