248 manifold for '50 Special

Either a 1950 or '51 or(& possibly a'52) (all Specials)
Possibly 1948 and 49 but I think the carburetor was re-designed somewhere in there.
If you find NOS you should consider yourself BLESSED! Unless I miss my guess, this part will NOT be inexpensive. If you find one chances are the owner of it will not haggle but want his price + shipping and CRATING. (Good crating is essential because of the part being cast, if it isn't packed right it will break in regular shipment)
Best wishes for your project!
I am a Buick Historian. I believe I have a '50 Buick (all series) owner's manual. I also have an ORIGINAL Dealer's Showroom Album in very good condition. I have owned it for 50 years!
If you are interested in anything to do with a '50 let me know. (I do not have parts anymore).
