Hi, I do not see any brand or part number written on these. However, it seems like crank 39-021 would be a good replacement for the same window's crank.
Thank you!

Greetings! The 38-056 and 38-057 Andersen Casement Locks look like potential replacements. If you need to replace your cranks and other parts as well, see our 39-020 and 39-021 Wood Window Cranks; our 39-520 12-1/2" Operator Track; and our 38-135 Andersen Casement Lock Keeper. See what you think.
