Looks like you have a '53 engine by the LA part of the code. I don't show a listing a Q, could it be G instead? LAG comes up as Passenger car, I have no btransmission breakdown on codes for '53, so a bit more investigation on casting numbers will be needed to determine if it's a manual trans or 'Glide engine. The 'Glide version is more desireable due to the full pressure oiling and more horsepower.
