GE 25 tonners

HI Folks
maybe some of you former LIRR folks can help me set the record straight.
In John Scala's book "Diesels of the Sunrise Trail", he only shows #398 & #399, NO #397.
I have been finding conflicting information regarding either the Construction Numbers or Serial Numbers of these 3 units.
The reason for this is that recently a GE manual for the GS1 "allegedly" from the LIRR was auctioned on EBAY and was donated to to Oyster Bay RR Museum.
Th front cover shows s/n #'s 33030 and 33373.
What we know is that
Oyster Bay RR Museum (OBRM) has #398/397 and the RR Museum of LI (RMLI) has #399.
According to Scala and every other source
#398 s/n #33303 was built for the LIRR
#399 s/n #33375 was built for the LIRR

Since this GE Manual shows both #33030 and we know it is #398, then s/n #33373 should be #397, which means it should have been built for the LIRR.
My research shows that (#397) s/n 33373 was not built for the LIRR but for the Lone Star Cement company yet other sources show it being built for the National Lead Company as
s/n #32628, yet it was built in 8/58 like #399.
I have gooten help for Dave Keller, Steve Lynch and Dave Morrison but now I am more confused with all the conflicting information. Can someone shed any more light on this subject?
Thank you
MADDOG

Greetings,
The 397 was purchased in the 1980's from LILCO in Island Park. The 398,399 were purchased new in 1958.

Morris Park #397 Sightings 1987-1989 MADDOG: Was it built in 8/58 like #399, as #398 was built 5/1958 serial #33030. (Perhaps the issue?) I have: #397 Built: 3/1956 serial #32628 for: Natl. Lead Co. of NJ
