Note:
The numerous Robt.E.Lees and many others were painted often as needed .The bigger packets were the luxury Steamers of their day. There were at least 8 Lees, 12 Natchez's, and 11 J.M.White's among others . Low pressure boilers didn't take kindly to safeties being capped for more speed .
It was at least a weekly happening in the Port newspapers to read of another steamer , Big or Small that had blown up! Some was from Plain bad maintenence too. As far as painting many went through collor changes as a matter of budget cuts aas well. I know of two Lees that were the colors of the Confederacy Blu-Grey Uniforms. One J.M.White was painted the colors of the Union battle Flag ie Red/White Blue.( See U.S.Navy 1860's)
Your Bunting looks good .The Fourth would still be Celebrated on these boats .Also something as mundane as Opening day of the freight and passenger season on the rivers ! Much Ado there .Boats hung with flags ,Bunting Calliopes ( if they didn't have one ) and Bands on the fore -upper deck. Dances and Cotillions once in port .
There were many that had one thing most models don't show .A Full rail around the top deck .Remember the Cabins on the Texas deck were sometimes used for " First Class Passengers " The further away from the Boiler deck the cooler it was !
P.S. I forgot to mention .I am taking the Natchez and the Lee and creating The Largest of the J.M.Whites on record . When Done I'll try to post it .
