CAM Identification ?

Have a cam in my 1968 400 that was purchased new in 1995 as part of a complete engine build and now am going through the engine again. Trying to identify the cam manufacture and specs as my builder back then did not save the cam information. On the shaft it has a CWC and a #1805 and A3 stamped which may be a date code there also is a white dot painted between a couple of the lobes.  On the gear end of the shaft it is stamped with three numberes H303, 930428, and what looks like an SP37 but the #3 is not clearly stamped it also has Pink, Green and Orange paint dots on the same gear end of the shaft.  Can any one out there lead me to a source for this cam info I have struck out digging for hours on the internet and Crane, Comp and Melling all say not theirs.  Pretty sure this may be a GM replacement cam but can't ID it so far it seemed to run OK with this CAM but sure would be good to know what I got back then or if I got shafted Shocked  it's the time to swap out.  Confused
Thanks for any input you experts can provide.

So nobody out there knows who might have made this CAM so I can chase down the specs or find out info on it? I must have got a real rare one lol from the Sonic parts guy that time here in MI.

HO HO Tis the season to be joyful happy holidays to all the Pontic guys/ girls out there.

I checked my ref books and can't find that # ---look on the back end of the cam for a letter...the 'H' you mentioned may be the identifier which would be a RA-111 cam.To be sure call around to an engine builder and ask if they have a Cam spec machine--for a fee they will run you cam and give you all the specs.
RA-111 specs are 301*/313* or 222*/234 @.050- center line 112*- lift .406"-5600 RPM

Only thing i can think of to do is several aftermarket cam manufacturers have historical data you can look up online. Crower does, Crane does and I think Comp Cams does also. You can run the numbers (I think the 930428 might be a grind number) and see if you get any hits at any of the sights.
