Need ID on Visibility Bubble

[old buffalo]

I recently acquired this perspex bubble at a gun auction. I've been trying to identify which aircraft it was made for but am having no luck. It's about 21" long and 11" wide. The label glued inside say CW-44 / APT 1006 Day - 44 : CAGW. I've attached two photos. Thanks for your help.

I'm not at home
but I'm guessing it's from a Curtiss-Wright bird
