So according to Mr Mikes dating list yours is a late 1940. Curious now what your serial number run is in relation to that date. Sweet bike!!!

I suppose the 4-quarter Morrow could make the @THEGOLDENGREEK bike a 1941 model?

What about maroon color?

My reasoning was this: the 1936-1940 Murray-built frames I've had and noted used the shim frame, and the 1939 Pacemaker ad shows shim frame.
Seems 1941 brought the "electroforged" seat-mast/clamp area using the 5/8" post w/o shims.
However, thinking back now, I had a 1941 boys Murray Elgin that used shims, and I think the 1941 Murray-built Miss America uses shims...? The Sears catalog shows both types of frames for 1941.
Now I'm thinking that both types of frames were made at the same time.
Another thing I've noticed from original Pacemaker-type bikes is that the fender differences seem to be consistent with frame style. Anyone else seen this?

I will confirm 100% your correct on that frame to fender difference statement. I have two bikes that don't have the seat post clamp over the tube style and they have the more peaked at the end fenders. The also have the the three cut outs in the chainring. The racks are also different at the mounting point,much narrower from the lack of the seat post clamp. The question now is why? Are they lower end models? Ones meant for off brands like Gambles and Western Auto and such? Different manufacturer? I thought they were all made by Murray???

I think these bikes look best in maroon. I believe Chris (@scrubbinrims ) has a beautiful men's Pacemaker in that color scheme.
