I think its a carter WCFB.  Just guessing.

Maybe off a 56 Merc

Sweet thank you and you could def be correct it has Mercury engine in it at least the valve covers any info is much needed

I agree with Paul and Grumpy.  It appears to be a Carter WCFB.  Two models of '56 Mercs used the WCFB carburetor.  All the other 312 Mercs in '56 and all of the four barrel carburetor applications on Fords used Holley 4000s.

What puzzles me on your carb is the choke plate.  I wonder if someone made a replacement out of something.  I've never seen one that looked like that on the numerous '56 Merc WCFBs that I've looked at.

Hope this helps.

Greygoose56:  I may be repeating what's in an earlier thread that you put-up ~ 3months ago...

IF this WCFB that you've posted the picture of is '56 Merc it is a one year, Merc only application.
IF the Carter ID tag is not on it, look for these items for verification that it is of '56 Merc origin:
- a 'spark control valve' between the two idle adjusting screws on the front base of the carburetor
- a steel vacuum line with attachment fitting on the front of the carb base just above the spark control valve
- a brass rectangular fitting screwed into the rear base of the carburetor that has two places for vacuum lines with threaded fittings to be attached
NOTE: the front vacuum line and one of the two rear vacuum lines originally went to the distributor on the '56 Mercs for providing the two different vacuum signals for the LoadOMatic ignition distributor.  The '56 Merc distributor ignition advance curve was totally actuated by springs and the two different vacuum signals from the carburetor

Hope this helps

Dang thank you again , and yes it is the same one got caught in life and back on the truck again, would you have a recommendation, am I better off trying to get a replacement carb or rebuild giving I believe that it is the carb that your describing out of the 56 merc

I found some rebuild kits for pretty cheap I'm gonna go ahead and do that thank you for your gait help much appreciated

hi! it could be a 56 merc or a 57 Lincoln? it definitely is for a ford product because of the vacume chamber on the secondaries. the Lincoln carb has larger venturies.

Greygoose56:  Food for thought...
Rebuilding your WCFB is certainly an option.
IF you gave me a '56 Merc Carter WCFB and a Holley 4000 with my choice of which to rebuild... I would likely pick the Holley 4000.
For me, the Holley 4000 is easier to work on and I'm more familiar with them
The Carter WCFB calls for use of a bunch of Carter made tools for those who do this stuff regularly.

Which ever carb you're going to rebuild, IF you need the instruction sheets from the manufacturer for the '56 Ford/Mercury Holley 4000 or the '56 Mercury application Carter WCFB, contact me using the Forum PM (PersonalMessage) system and I'll send you photocopies of the information.

Along the same vein, IF you use either '56 vintage carburetor, consider eliminating the '56 LoadoMatic ignition distributor and substituting a '57 and up Ford/Mercury y-block ignition distributor.  While you would not have the correct vacuum signal from either carburetor to use the vacuum advance mechanism provision, the centrifugal advance mechanism will perform completely flawlessly and provide satisfactory performance from whatever your application.

Hope this helps.
