Nice find on that crankset. These are getting more difficult to come by.

Im counting 39 teeth on the small ring which leads me to conclude this is a later model 130 BCD crank. It probably uses the 112mm spindle length you read about on velobase. Using your 109 will change the chain line which can cause issues getting into the highest and lowest gears. It will also lessen the clearance between the crank arm and chain stay by 1.5mm per side. Creates a possible issue with contact particularly from any flex under load. A more extreme decrease in spindle length could cause the crank to hit the bb/shell housing but doubtful at 1.5mm per side.

All that said, no harm in installing it, measuring the chain line, confirming shift quality and clearance. It may work fine.
