Lee Enfield Aluminum stock

[Thunderbox]

Rather than these ally bits being a cast copy of the wood forearm, could the ally forearm actually be the pattern to make the wood? I've seen ally patterns where the machine follows the line of it and cuts the wood copy exactly. I wonder if some ones got a hold of some and fitted them to rifles? Just a thought.

The pattern for No4 butts (in a photo of Long Branch factory) and L1A1 butts (photo from Enfield) show that those patterns were about 200% size scaled.

I assume that forends were probably cut from at least two patterns - an inside and an outside? Given the type of machinery at the time, i imagine the forends were shaped in multiple operations.
