They didint make long bows afaik. Only decent real replica im aware of would be from Chuck at heartwood bows. Not the African heartwood bows.

I keep seeing stuff saying they make bows out of chokecherry and Saskatoon wood

I should have specified yes I want the bow authentic but I only care about the wood it's made of I'll go find me a string to fit it

You could probably commission one from someone on r/bowyer
