Help ID a distributor

[Stucat]

I have 2 distributors 1 has a ID tag 2875772 ibs 4014B , the other has no ID tag, but is 98 % the same, the only difference is it does not have the O ring grove at the base that fit into the engine block. Would that be an earlier year, both have the 69 vac advance style? see pics Thanks

Looks like its a Job rated distributor? for a 318 Poly. 65/66 Check this one in this link. Yours is an Autolite.

For Sale - 1965/66 Autolite Distributors Poly 318

I have 2 Autolite points distributors available 1 has new points cap and rotor The second looks to have been rebuilt or reconditioned in the past but cap and rotor are mildly used Both have leaky vacuum advances unfortunately Both appear to be perfect candidates for electronic conversions...

4014B is 1969 440 4-speed

I was wondering which ones have the o-ring also. And I figured the o-ringed ones didn't use the gasket but I have no idea if that is true.

O- rings started in 1969 model year.

@HALIFAXHOPS is the distributor guy....

Yes the 440 4 speed is a 69 dual point setup, both distributors are dual point and the shaft length is the same, both have IB21castedin the bottom and 2 holed next to the casting

 

[Stucat]

Are there any way to tell if its a 1968 dual point and what engine it would be for?

Non O ring that used a metal gasket usually pre 68, no way to tell till you take it apart and tell the part numbers and clocking. Only in the prestolite parts books, no idea why the IPB did not use the prestolite numbers! Just FYI all the cast Iron housings have those mumbers on the castings. Band RB and LA are the same just machined differently.
