Thanks for the interest and nice comments lads. This has been a labour of love since first being bitten by the "Sherman bug" back in jan 2009 - its being going on and off since then!
Tim Perry of Fighting 48th did a superb job in bringing a really nice number of conversion sets ( M4A4, various tracks, ammunitions boxes, decals and figs ) to fill a void in the Sherman builders tool box. If you ever get a chance to pick up any of his items... don't hesitate as you will be rewarded with accurate and well designed items that will add that extra bit to your Sherman build.
Going silent - be back in due course
