Quick Boardway limited K4 question...

I am 99% certain I am going to pick up a Boardway limited K4, can someone tell me what the difference is in the 2 models, I have no idea that the slatted or cast pilot is or where its located.

Paragon™ Series Platinum Steam K-4 4-6-2 w/Quantim™ Sound – Pennsylvania RR #623 Slatted Pilot, Generator On Smokebox Top

Paragon™ Series Platinum Steam K-4 4-6-2 w/Quantim™ Sound – Pennsylvania RR #3751 Cast Pilot, Generator On Smokebox Front

Thanks, Ed

I believe these links to the Bachmann K4 give you a better view - the slatted pilot is pre-war and the cast pilot is post-war. BTW, it’s the loco’s front bumper! [:D]

Please correct me if I’m wrong, anyone.

Thanks! Either way, I like the pre-war version better.
