If it's the one that I had given to me, then it's made by Mardon Models back in the 1980's when Tom Gorman was a director of the company. 2 versions were made. One has a GRP hull and the other was POF.
I have the GRP version, the kit is almost complete and what was missing was brilliantly explained to me my Tom Gorman himself - a real gent.
I believe historic models purchased some of the plans from Mardon - but I may be wrong in this.
It is definitely a true modellers model as opposed to the kits on the market today. Most of the timber is roughly cut to shape leaving the modeller to finish shape and fit.
Fantastic quality though and will make a great looking model when I get the chance to complete it.
Hope this is of help.
