1888 6c Stamp With Perf 12.1 As Gazette Printing At Sparks

Hello,

I found this stamp auction in the archives:
https://stampauctionnetwork.com/IK/ik194.cfm

(can't link directly, the number of the lot is 165)

From what I know the Montreal Gazette printing was perf 12.25 at two sides, not 12.1?

Also, in the Unitrade catalog for the year 1888 it says for the 6c "none printed" in the small queen overview.

As the stamp comes from V.G.Greene I guess there is some provenance to tell it's a Gazette.

So are there other stamps known to be printed there than the listed 2c and 3c and the possible 1c and 5c?

I still did not find an answer to this. Sadly BeeSee is not here anymore to give his opinion.

Am I correct in thinking that only those stamps were printed in the Gazette?
- small queens 2c (#36d), 3c (#41a)
and this one:
- 2c Registered (#F1b)

and maybe, but without defining color:
- 1c and 5c (no Unitrade #)

But what about more stamps to be printed in the Gazette?

So in the link above we have in addition:
- 6c (#39d var)

And here I found:
- 10c (#45 var)

In another source (I don't remember) I found that the 10c lilac/pink was printed in the Gazette perhaps.

Until I saw the 6c stamp, I thought Gazette printings were always 12x12.25. But Sparks defines it as 12.1.

So what are your thoughts, are there any stamps, other than the three at the top if the list, that really could one day find their way as Gazette printing into Unitrade?

Do we have to have a 12x12.25 and a special color to say it's a Gazette printing?

I think that Jim M sometimes posts to this site however he is on vacation at the moment. I managed to get an email to him about this. His answer:

"... Perf 12.25 by 12.1 and the inverse may be an indication, but that perf combo also exists outside of the Gazette printings. Ted Nixon was studying them, and may have more info. I think he identified a shade which could identify Gazette, but when we discussed it he was not sure how to prove that."

It may be possible that Ted has figured it out by now. You may want to contact Sparks or Ted to get further information. Jim M has studied the 6c SQ specifically for many years so I would believe what he says.

Thank you very much for reaching out to him. The point is that Sparks did not define this 6c as 12.25 by 12.1 but only perf. 12.1. So no 12.25 at all :). That's why I asked about if the 12.25 is a necessary condition to be a Gazette (not the other way around, of course). If you would like to add this in your email communication with Jim, this would be great, just to clarify this if it was misunderstood.

to summarize:
The small queen 2c, 3c and registered 2c is obvious, being 12x12.25 and there is a specific color.
The small queen 1c and 5c do exist as Gazette (12x12.25) but no own color (probably).
Those above seem easy.

The small queen 6c and 10c appear to have people who believe in them :).
But as the 6c and 10c (and also the 1/2c and 8c by the way) were not printed normally with a perf. combination with 12.25, for those stamps, the 12.25 indeed could be the indicator for Gazette?
