Thanks for your response Grip
No I never kept it and was going to bid on them but got busy & forgot all about it. Then it was too late so just deleted it. I did speak to the chap at House of Darts regarding the stems but the die that they cut the tops from is now so old that he is not going to update it and the grooves in the top are really wide now from wear & tear on the die so you need a minimum of 100 microns just to keep the flight in the top & to be honest they do keep coming out rather than gripping like the originals did. I know the Yellow ones were old style so that's why I wanted some as the grooves will be tighter either that or pick up some old Red tops. The stems are even different and he told me that is due to the amount of fibre glass that used to be allowed in the stems back in the day, where as now the stems are not so shiny and are more of a matt finish. Despite my lengthy conversation with him I forgot to ask him if the Yellow tops were his so I will go back to him and ask.
