Master Model has produced a replacement nose pitot for the Trumpeter MiG-21 F-13 Fishbed kit. The replacement pitot is a clean drop-in for the kit’s plastic parts. The supplied items include a two-piece main pitot tube of turned stainless and photo etch brass vane fins.
A side-by-side evaluation (see photos) indicates an identical replacement that provides a much more realistic assembly with a significantly improved abuse tolerance. Painting of the main tube should not be necessary, but the fins will need a quick touch with silver or red to transform the brass. Check your references
