Beautiful blanks. They appear to be Claro with the second from the top possible Bastogne. Batogne is a cross between English and Claro. They can be recrossed for at least two more generations. When this is done, the resulting wood gets closer in looks to the most dominant parent. You can also see the English in a part of one blank with Claro is another part. Makes for interesting blanks. Sometimes, like English, much of the Bastogne tree can be as white as maple. This is not sap wood.

The top two have the forearm grain going upwards instead of straight, but that is OK. You don't want it going down for accuracy reasons. The third might better be a two-piece due to the forearm. The bottom would be fastest selling for many people. "Winchester" feather pattern as it lays now. The advantage of English over Claro and black and Bastogne is machinability. The others tend to chip. English can be worked faster with bigger teeth with less care. English is also less dense on the average and better for lightweight game guns.

Circassian has gotten a good rep over the decades. The dark lines are wide; it is dense; and the color might be best described as caramel rather than the yellow of later French. Early French was dark grey. Favorite producing types change over the centuries. Current French is mainly "Francotte". Circassian resembles "Mayotte". There are very many varieties. They are all Jurglans Regia. These include English, Himalayan, Moroccan, Turkish, NZ, Australian, etc. The densest English in the experience of David Trevallion is Australian and West Coast USA English. Of course, density and other characteristics overlap and age adds "temper" which hardens the blanks. This is not so important to stocks but adds tone and is better for musical instruments.

Prolly more than you wanted to know.
