I know its not a great deal of help but I beleave that these where rebadged tascos (with the xmas tree reticle) sold by Ramsbottoms in the early 90's. I baught one of these in the early 90's (think it was about 93, a 6-24x44) and to be honest it isnt a bad scope, springerproof as I had it on a Mk1 TX200 I had at the time.
Hope this helps
