ok heres where i get confused.....first off lets start here...the guy said he bought it brand new in 1956, the serial number i believe makes the tractor a 55...ok i can believe that it was manufactured one year and sold the next....serial is 28735 - 702.....whats the spec # mean?  Mine is 17-1424.....ok now being we know it's a 55 model, bought new in 56....the original manual i was given with red cover in the lower left says issued 11-1-54. and in this manual on page 1-3 it shows a picture of &quot;HC controls&quot;  and it shows an ignition switch in the picture below the dash just to the right of the hydralectric plugs.....the switch looks in the picture exactly like mine on my tractor...in fact i checked my tractor and it has a hole about where the pic shows the switch to be....and i seen a dash picture of another tractor and it had a &quot;knock-out&quot; where my switch is mounted now...so if they were printing it in the picture of the manual in 54 i would think my tractor could have possibly came with it?  and they decided to move it to a more convenient spot?   wow i love researching and digging into new things but info is much harder to find on these than on the AC's i am used to dealing with.
