as you probably know, there are examples (not in that model) of all three combinations. The lighter /med blue combo is interesting too. I think I have a photo of a 180 with it (I remember the car had a refrigerated bar too)

plus the earlier ones generally use the lighter color on top to visually lower the car.

thanks - I forgot there is an "early" and "late" set of green/brown/blue top colors. I don't think I've ever seen the two tone green on a car (although the single color green is common enough. I don't think the combo's on the 22nd are as attractive as the 19th - 21st ones overall.

time for me to learn:

what are the other 22nd 2 tones?: I'm familiar with Serpentine green/golden green, Agate Blue/Egyptian Sand, Lexington Green/ES, Sardonyx Brown (later Aztec Brown)/ES

acknowledging that it's your car and you can paint it as you wish, be aware that the color combinations the factory offered are quite limited. You can work them out from a paint chart. I'm more familiar with the 22nd combinations (3 top colors over Egyptian Sand, plus maybe a two tone green)but many combos you may have seen and which make sense were not factory options if that matters to you. I don't think there was a Blue Lower combo after the 21st series

key question for the business case: what will be the regulatory classification and therefore how will one meet the environmental and crash specs? Big money question

Have you seen a locksmith? They can make a key for a lock - I had this done for a sidemount lock, he viewed it as routine and cleaned and lubed the lock while he had it

many Packards have over restored trunks.

The fuzzy polyester interior is indeed expensive to fix.

look closer - not a bathtub (22nd-23rd) but a 21st

I believe that the swan neck mirrors that fit into the belt molding are 21st and 22nd series, and that the 23rd mounts conventionally to the body
