Bill,
I assume you mean the MM1350 plan by Richard Webb.
I vaguely remember seeing something about it in Model Boats a long while ago.
I think the only way to track down the article is for those of us who have back issues of the magazine to use the plan reference number to ‘bracket’ the likely issues and try and track down the article that way. This is a bit of a time consuming task as you might imagine!
If I have some spare time over the next few days I will have a look through my copies.
