Longbow - what year?

[Tozama]

Playing another English - early campaign and have been building up to what I thought would give me longbows in high.
According to a file I downloaded called MTWBuildingandUnitData.pdf I need castle, townwatch and bowyers guild, be English and high or late period.
I have a Citidal (whatever is right after castle), master bowyer and Town Militia.

Ok great. It's 1202 - no Longbows????
I recall high period was 1200.
Yes?
No?
