Sorry to disagree with your assertion that I meant "original WM Intruder". I meant original in that it was the original kit I bought and flew in the 70's. Don't recall who actually kitted it. The photos are scans from my 35 year old slides. I have not personally seen a WM Intruder and I have no opinion on how closely it represents Kirklands original design. As far as modifications to the original designs goes, I agree that many, if not most, have had some modifications. That's what we did when we built kits in the 70's too. I only have trouble calling it an Intruder, or a Dirty Birdy, or a Phoenix, etc...... when the design starts becoming unrecognizable.
