Hi AG4108 I would like to change the tray to oxidation as early as possible if there are no complaints. I was hoping to ask Len to change it today (Wed Nov 21) at 2 p.m. or monday (Nov 26) at 6 a.m. I see that there are no reservations except for Uli's Nov 29 from 9 -12. Please let me know if this is a problem Thanks in advance Helen Kung
