Very nice Holley Carburetor Model 4150 For Ford and Mercury Service Manual. 1956 edition. 35 pages. Lots of great information in this booklet.

There is some shop wear but very nice condition otherwise.

You have 2 shipping options: free Media Mail, Ground Advantage for $6.50, or Priority Mail for $9.50.
