Store branded, Gale produced. Forget who sold them, but they are an OMC product. 5 hp was available too. Edit: Here you go Johnnyrude, Spiegel catalog offering 😉

I own one. Mine is the 13th one made (150).. They were only made for about 6 months and abandoned for bigger profit from the 3 (300) , 5 (500) and etc. 1950-1958 Spiegel sold some Neptunes pre 1950. Spiegel also bought an auto parts place , prominent in the Midwest called J & R Auto Supply and sold all the motors thru them. I am putting an extensive collection of information together about all the Gale motors and especially the little guys , 1.5 HP. This includes advertising , catalogs, sales brochures, , newspapers , etc. I will submit it to AOMC down the road. PS they made some interesting upgrades for the 1,5 HP (150) Brooklure unlike all other 1.5 HP Gales.

I thought I bought them all up? Olson #1 ? You can make them up with brass rods, obtained @ Loews.It appears everybody likes those big guys and my dream this summer is to strap three of them on my Grumman Sport Boat !!
