Timothy Richards is a British gentleman that makes architectural models of historic buildings for a living. His website is packed with interesting photos and it seems a lot of the techniques he uses are very similar to your average tabletop wargamer’s.
His prices are eye-opening though! For example this particular piece sells for 650GBP or $1620NZ at today’s exchange rate.
Wow looks like a good weeks work plus there . Wonder what it would look like , after going through New Zealand postage ? Proberly not worth 6 weeks wages to find out ! :-)
