I also think Brooklin did a fine job on these, with one minor omission:
Olds used the B-44 designation to celebrate its 44th year and to capitalize on the war-related designation of the capital "B", as in B-17 and B-24. The B-44 logo was located on the upper part of the grille, on the driver's side, above the letter E in the brand name (also red, and also missing on the model although the letters are very small and would have been impossible on a 1/43rd). The "B-44" logo is only shown twice in the original catalog and they're obviously retouched on the artwork, so it's inclusion on the car was clearly a late decision. The cars in the brochure don't have it, but the one on the cover and inside cover page do. The logo is bright red, and would have been a colorful detail to add to the grille.Otherwise, BRK gets an "A" for these Oldsmobiles!
