Hmm. I ordered an FTB48 just last thursday and the dealer said it would take a week. Who told you 4 to 6 weeks? Maybe your dealer is waiting until he accumulates enough WRLong orders to fill a truck in order to save on shipping cost.
I guess I saw that at the WR Long web site. I asked my dealer not to have it delivered by Long until after the 17Th since I will not be at my summer home in Montana until then. The dealer is ordering shipment direct from Long since he is listed as a dealer for Long but he does not stock any Long equipment.
