Those Deluxe front forks/ action don't look anything like the forks on Keiths dads' bike ?
No sign of pedals either ?
What's your suggestion then as to the make of the bike, a Harley?
But you are right, the front forks lack the leaf spring and linkage and the front fender looks heavily modified. The front axle now rests directly in the slots for the spring links - the front wheel is about two inches too far forward now, just the length of the missing links!
But I can still see the second chain on the right side of the bike so the countershaft for the pedal crank is still there. If the pedal isn't just obscured by the rider's leg but really is missing completely he would have to push start the bike as there is no gearbox and kick starter. And where would he put his feet while riding?
The production of the Spacke engine for motorcycle use ended in 1919 at the latest, so if this photograph really was taken in the mid-thirties the bike would have been 15 to 20 years old and could have stood abandoned and partly dismantled in a barn for the last ten.
Maybe the young man found it, cleaned it, put it back together as best he could and just took it out for fun and the picture. If you look closely there seems to be no twistgrip on the handlebar as well!?
Anyway this is a great period pic. Thanks for sharing, Keith!
Cheers
