Pete Allan had/has a number of useful casting patterns that apparently - after he either retired or shut down his business - he will not sell. I don't know him but that's what I was told by the folks up at Track. They used to stock 'reconversion' parts from Peter Allan; there were two different sizes of cocks, frizzens and pans. They were VERY useful castings, well made, but now nobody can get them and I've used up almost all of what I had left. I particularly miss the frizzens.
