I've always liked the lightened Long Branch No 4s, and thought I'd try to make a facsimile. I reduced the stock and inletted the lightening cuts and replaced the foresight with a P14 version. I've still got to add the rear sling swivel, and a cross bolt when I find an appropriate one, but I'm really happy with it. I haven't lightened the receiver for obvious reasons, but the rifle is considerably lighter than a standard No 4.
I should add that I will not be trying to pass this off as the real thing, and TBH I don't think I could. There are too many differences to fool anyone with any research skills or knowledge. Just an interesting experiment for me.
