Scott 733 Versus Scott 753

http://www.shaulisstamps.com/tips/FarleyIssues.htm

After reviewing that link I'm still confused. The stamp on the left is gummed leading me to believe it should be a 733. But it clearly has a line along the bottom, which I assume is a guideline. That link says guidelines were added for 753.

The stamp on the right has no gum but does has the faintest touch of what is likely a guideline along the top perfs.

Can a Scott 733 have a line along the bottom?

Remember this from not long ago?

Harpo,
The information on 733 vs 753 in the shaulis link you cite is so full of errors that you should ignore or forget everything it says. Period. Use the link in rogdcam's post instead.

1.The press sheets of both 733 and 753 have guidelines. They come from the same 4 plates.
2. 733 was issued gummed in panes of 50 cut along the perforated guide lines, while 753 was ungummed in full press sheets of 200.
3. 753 was *not* among those Farley issues which could be sent back for regumming.

Thus:
A. Your first stamp will be a single from a pane of 733 due to the gum.
B. Your second stamp could be either a soaked 733 or a mint 753, unprovable to either.
C. To have proof of being a 753 it *must* straddle the guideline, thus requiring a pair or more. (And yes, many of the 753 FDCs don't have a proveable 753 on them!!!)

An anomoly which occurs in the Scott listings on several of the Farley's is the gummed plate block of 733 (CV=$12) could be soaked to become an ungummed plate block of 753 (CV=$15), in the 2020 edition. Oops.

As a tangent, it may be impossible to tell which version is on a cover, but in this case it must be 733, because of the date of use, March 9, 1934, being before the Farley releases. Note the guideline along the bottom of the strip.

John, what do you mean by 'straddle' the guideline? If both issues are identical, other than the gum on the earlier one. Couldn't both have 'straddles'? Gum would of course need to be removed from the later issue to mimic the earlier issue.

I'm new and still waiting for my ah ha moment.

Bold added by me

No. Same plates, but difference in both gum and cutting.
733 is cut along the guide lines into panes of 50 for retail sale.
753 was sold in full press sheets of 200, thus you can get pairs (or larger) which show the guideline between stamps and prove being a 753 (as opposed to possibly being a soaked 733).

The two stamps "straddle" across both sides of the guideline on 753...

The center of the sheet of 200 is where the two lines cross and is a nice premium piece, which I don't have handy at the moment, but are readily findable on ebay, etc.
And a pair of 753 on a non-FDC cover, rather uncommon.

No offense, Rogdcam, but links to ebay soon go inactive. Please post screen shots rather than links.

733 pane of 50:



There really is no practical difference other than gum. Yes, the 733's were distributed in panes of 50 but there was no special "cutting" taking place. There may be full sheets of 733 in the wild. The two Scott numbers are the SAME animal save for the gum.

This topic always becomes unnecessarily obtuse. Keep it simple and it all makes sense.

As per John's request:

OK. I think I understand now. 733 was only issued in panes of 50 and the stamps from it can only possibly have the guidelines along one edge. 753 on the other hand were made available in larger sheets where connected pairs showing the guidelines in between are readily available. So, if there is no gum and a pair has a guideline along their perforated connection, must be 753.
