Today the ehattons.com web site has this to say
Our Price: £46.00
371-062 Graham Farish - Class 03 Diesel Shunter 03066 BR Blue with Wasp Stripes & Air Tanks.
This is our top selling product from the last fortnight!
Don't think I can remember that ever being something other than OO before
Hopefully, that's really encouraging for the manufacturers. The red stripe railfreight and blue Dapol 26s didn't seem to hang around either.
I can't say that surprises me - I tried to get one relatively early at Warley on Saturday and couldn't find one.
Best get my order into Hattons soon!
Anyway that is excellent news
