The little pieces that stick in front of the engines are vortex dissipators. If you see the 737-200 on a wet runway, you can sometimes see a vortex of water entering the engine. Because these planes were for use out of gravel strips, the dissipators break up the vortex and prevent gravel from being ingested into the engines. CP's examples of this type also have a ADF antenna running from the tail to the fuselage. I think it's a sense antenna, I always get mixed up between sense and loop antennaes. These are found on the 737-200 combi.

Nothing......Everybody else beat me to identiting the gravel kit........
I do want to add that kit is the reason why Alaska will not be retiring the 737-200's anytime soon.......They are operated as combis up here and pull some really serious duty...........The rumor is that Alaska has had the money in the bank since they bought 746 to get another -200 combi but none have come on the market.........
OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.

I believe this "kit" (nose wheel plate that prevents stones being picked up and thrown into the engines by the nose wheel, and the inlet dissipators) was designed by Pacific Western in the early 70's for use on northern Canada gravel strips. Or perhaps it was Nordair. Regardless, both operators used this 737-200 mod extensively for 25 years.
