West Point 3-Wheeler Truck/Cart???

[BCS9287]

Hi everyone, my names Brad, this is my first post on this site. I recently purchased this odd looking 3 wheeled truck. I found it about 5 miles from where I live by mistake. I actually work on small engines as a hobby and buy fix and resell lawn tractors to fund the restoration and upkeep of my old tractors that I take to shows and what not. Anyway, this is how I stumbled across this West Point 3 wheeled truck/cart.....I was taking a longer route to a guys house to pick up some lawn tractors when I seen this along side the road for sale. I was able to get the guy down from the $350. asking price to $275. It runs and drives but definitely needs some TLC. It has a 12 hp Kohler Engine which im used too seeing in some of my tractors I come across. It does run and drive in forward but not in reverse unless going backwards down hill. It doesnt charge the battery, needs a new floor for the bed and not to mention a paint job. I took a bunch of photos yesterday and will post some below. I am trying to find some info on it and am having quite a hard time. Also I dont know anything about this forward and reverse transmission. I have to slowly engage the transmission into forward to move almost like engaging a clutch?? If I dont move it out of gear and into nuetral I cant stop it. Is this normal?? Im new to these things....
