To be honest, if I had a say in the matter - and I don't

I'd like to see the 15s having a well-earned rest & for a good while...

I'd much rather they did another run of 33s 38s 82s 92s. But there isn't the collector frenzy around this I suppose. Moreover, it would be nice for GEC to produce something new for a change, OK the 44 Gunstock will be a new pattern for them and that is good.
But how about a Coffin Jack? A Teardrop that isn't Candle Tip? A proper Small Stockman or Sleeveboard? A real Norfolk and not that tiny Northwoods effort, an Anglo-Saxon, Large Pen?? GEC used to revive patterns, now they revive the 15, constantly. I understand the economics of it but it could lead to diminished interest if they're not careful
As for stainless, it seems it died out in 2016..nothing last year and with Queen dropping out of the picture it looks like extinction for non carbon
