Dave Fritzke, who frequents this group, has a great web site with all sorts of old timer plans including the Roughneck Too.

I emailed Lanier, who now owns Goldberg, regarding the Jr. Falcon and Jr. Skylark and they said that the plans were gone many years before they purchased the company, so I doubt that they will be kitting those models again.
