Its obvious that there is heritage of heavy bows for war in the area far before actuall english assimilation of longbow as main artilery armament.
Hehe.
Also from iconographic source we can tell the bows were bloody heavy already by the half of the 14. century, because the archer postures and drawing style is typical for heavy bows. Also the nocks have been probably present at that time as some sources show it quite clearly.
Of course it should be medieval warbow, nothing else. Calling anything else by that name, is degradation of the real thing.
The military use didnt actually lasted so long. Its safe to frame it by big battle events.
Hallidon Hill and reconquist of Scottland by english was time of forming the tactics, logistic and the technical advancement of the weapon. (First leap.)
This is first third of 14. century. But at Crecy this all was already functional. Its clear the advancement due to arms race was quite rapid.
The other leap occured around the time of Azincourt, or better yet around half of 15. century when plate armour was readily availble even for non-nobile combatants.
Last major battle event is Flodden Field. Mary Rose bows are last of the line. After Mary Rose, the bows have been still of some use in skirmishing even as late as english civil war, but we can safely tell it was a swan´s song only.
English bow does not need 32´´ draw, its obvious not everybody can reach it and even at MR was alotl of arrows shorter than this.
It is defined more by performance than anything else. Also the draw is not defined by obscure "english warbow should have 32´´ draw" but more by limitations of frame of said archer. A sporting style of draw is not acceptable, where a "stand in the bow" style is.
We can probably discard the requirement of linen and hemp string due to fact that neither material is availble in necessary quality anymore, but we should stay purist as much as possible.
I m very much responsible for recent popularisation of shooting heavy bows, but we should not degrade medieval archery by calling everything "warbow".
