My thoughts:

Engine number: A17646B (listed on reg papers) - ???????? In same series as that below, maybe there was a replacement engine installed at some stage?
Chassis number:1182 12957 (listed on reg papers) - body Number 1182(1938 Six 4 Door Touring Sedan) 12957 (Body sequence number)
firewall number: 424 623 - Theft Proof Number, Dave will be able to provide more on this
number on right hand side of engine block: A12237 - Engine Number Series for 38 Six is A1501 -> A36600

Because it a '38, these had decals on the firewall with the relevant body/sequence numbers on them. However, being a decal, not many have survived the past 80 years.

Dave, when he comes along, may be able to provide better insights.

Just a comment on 1182 12957; it's a vehicle number, not a chassis number.

Theft-proof # of 424623 confirms the car is a 1938.

I believe Ozstatman is correct in it being a replacement engine. The A17646 engine number would place it as a 38 engine but the B suffix indicates there is something different from what was originally released or spec'd in the car or engine. It could be something like a different mechanical brand or design part in the engine or a different clutch in the drivetrain or an oversize something so as not to waste a casting because some hole could not be machined to a smaller spec. The A12237 number and lack of a suffix in the current engine means it is also 38 but was produced earlier and built as originally released.

As far as I know, no comprehensive review or charts have been made of the various suffixes used and their meanings over the years but most have been called out in detail in various service letters and counselors. If you wanted to go thru the articles starting a year before to a couple after the model year you could probably find the suffix to see what is different. The service letters and counselors are available for free download at http://www.packardinfo.com.

Suffix "B" for 1938 Sixes and Eights indicates a sourcing change for the camshaft, a forged steel camshaft rather than the cast nodular iron shaft. In the course of normal car use there is no significant difference.
