That's sad news Stalker
Will, I guess it's really it's own thing. ALBs I believe are characterized as flatbows, which this is not. Since it's light weight, and not yew, it really can't follow the victorian ELB rules, but it is a d section, narrows evenly from grip to tips, and has a more circular tiller (except the stiff tips, mind you). No one really knows the design of Welsh Longbows historically as there are no artifacts. But if you folow the ideology that the ELB in its war form took cues from the Welsh Longbow, and the Welsh Longbow was made of elm (of that much we are sure!), then I don't think this is a stretch to think this one is very different. If I could have made it quite a bit heavier, it would have bent thru the handle and had a rue circular tiller. That was my reasoning anyway, inspired by the WLB, so I called it a WLB
Well the Ballinderry bow was early Irish Viking, and the Mary Rose bows were late medieval, and both are almost identical - circular or "galleon" cross section (not D section - that's a Victorian addition as well, funnily enough) with no distinct handle, fade area or stiff tips. It stands to reason (and is the accepted belief amongst the traditional longbow/warbow community) that pretty much all the English/Welsh military bows inbetween the two eras were the same as well. Welsh bows were made of any indigenous woods - wych elm, hazel, holly, yew, plum, ash etc etc.
I reckon what you've made is more Scandinavian than Welsh - similar to the Haithabu or Holmgaard bows.
