decode 1951 chevy trim tag??

I have had no luck finding a site to decode my 1951 chevy sedan delivery trim tag......

Style# 51-1271
Body# CL 17650
Trim 163
Paint 447

Any help??

trim # 163 = brown imitation leather
paint# 447 = Trophy Blue
Body#511271 = Sedan- Delivery Styleline Special

the style no is not listed but it is a Styleline Special.
