tonyt, I'll have to get some info from you regarding the mods / upgrades that you have made to your Tommy - as a bit of inspiration  

I have not started the restore on Tommy, enjoying playing it too much. The only visual thing I have added is a topper. Not a big fan of toppers generally, but think Tommy's really suits the game. Have not been able to find an original topper, so purchased one of these http://www.ebay.com.au/itm/4x200mm-Stainless-Steel-Pond-Garden-Decorative-Ball-/320777466312?pt=AU_Decor_Furnishing&hash=item4aafd3b1c8. These are 8 inches in diameter and from what I read, the originals were 7.5 inches - so pretty close .
