Plow numbers

I saw the answer to this a little while back but can't find it now. Where do I find the model number on a #73 plow. I think it's a 392 but not sure and I need some new shares.

You need to find a part number on a share, shin, mold board, frog, or landside of a plow bottom to let us look up the plow bottom number and then we can list the part numbers for the several optional shares (long and short points, rock  or soft center, cast or forged, deep suck, regular suck are most of the variations), then you can hunt for shares.

The plow bottoms assembled are illustrated in the plow bottoms book as seen from the bottom laying on the landside. Sometimes they are distinct enough to identify from that photo. The plow frames are fairly distinct. 50 has vertical fixed shanks, 60 has slanting fixed shanks, and there's no provisions for changing the width of the plow frame on these two, 70 has two piece cross bars with extra bolt holes so the plow frame width can be changed, 80 has that width adjustment and spring trips on the shanks.

I think the 392 bottom has a shin with three bolts, unless I remember wrong that's what is on my 2000 monobeam plow. Newer than a 70 series, but still the same frog mounting bolts.
