More on the roof top light ......     Since your Grandfather was an AAA emergency service provider, this would have been the roof top sign/light that is pictured.     For more history info. look up Gillco out of Philadelphia ...they where the company making these type of signs back in the day. 

I found two other areas that are unique.....   The roof top...that looks more like a lighted sign (think taxi cab) than a beacon.   This looks like a cold air primer/starting aid (at least that's what we called them in the maintenance section of the Ks. Army National Guard)  Looks like there is a pump handle...either or ethyl would have been in the cylinder. Looks like there is a rubber hose running back under the hood.  

Great information. I would not have caught that. Thank you. I know little of that era of trucks. In fact, I didn’t even know he owned a service station until I found that photo in a box of old photos my mother brought me a couple weeks ago. He passed away a just a few months before I was born, and I’m his namesake. Now at age 46, you can imagine my excitement and surprise at finding a really cool truck with his name on it. I had no idea all these years. My mother was young at the time, and she doesn’t remember much about the Sunoco station. A future tribute build is a must.

I failed to add this to the paint colors......I don't know if you saw this or not....   This pictured shows that it is a P.T.O driven winch and not a hand crank.  If my memory serves me correctly, this would be a chain driven winch (transfer case - chain drive - winch)... the Holmes units of that era were chain driven as well...similar design....if your going to be building in that much detail.  Transfer case would be like the smaller transfer cases found on WW II trucks (2 1/2 ton and below) JEEPS etc. etc. 

Great progress!

Thanks, that’s helpful.

Found the colors that Ford painted their trucks in '41   ......  the darker blue and maroon colors would look great w/ the Sunoco logo and white lettering IMHO. 

Finished up all of the lights on the tank......   Little bit of everything here.  Ranger Detail Technologies Rectangular Slam Locks and turn signals.  The turn signals were an extra that Tim threw in the last order.  They look to be the front turn signals from the 1/25th Scale 1976-1978 American LaFrance PIONEER III Cab Kit...looks great no matter what they could be used on....if interested, give Tim a shout, I am pretty sure that he could print up a set at a very reasonable cost, tell him you saw them here. The 3 red marker lights and back up lights were done using a hand held hole punch.  The brake lights are from parts unknown. `    More marker lights using a hand held hole punch

Thank you very much. I’ll gather more info on the Manley brand. This has been a very cool discovery for me. Up until today, I had no idea. He passed just before I was born, and my mother brought a large box of old family photos with her this weekend, and this one really caught my eye. When asked she said “oh I forgot about that, yeah he owned a gas station at one time…”

1941 Ford 1 ton .....wrecker looks to be a Manley, definitely not a Holmes unit.
