Mark;
Don't know how you could have passed on that one.
It appears this is a two-hook model with plate mounted sears. I am going to assume he put an extra X in the SN & it is 18,78x rather than 187,8xx as stated. Lefever SNs didn't reach 100,000 by close to 30,000.
The 10ga is a good solid shooting gun, just don't expect wild miracles of pattern improvement. That vast difference of column height, if loaded with 1Ľoz in both gauges the column will be just about exactly shorter in the 10 by the dia of one #7 shot (.100").
