what is it? 1900-1901. sn 49xxx

Geno, Do you mean a Greener Grade 1? I have a Greener 10 gauge #1 delivered in 1883 to a Mr. Wyndyat who ordered said gun with tang safety. It has what is referred to as Silver Damascus barrels. I sent the barrels to Mr. Dale Edmonds for "blackening" he did his best but to be candid the steel content is so high that little of the iron color contrast was raised. It is my understanding that the #1 was one of Greener's highest grade guns in it's era. Mine has the Facile Princeps action. Serial # 30XXX. My gun has a weight of 9 lbs 14 oz. , 32" barrels, 3 1/4" for brass case chambers. I acquired it from a collection where it had resided for many years and is in excellent condition. Mr Graham Greener graciously provided me with a letter advising much of the original configuration detail. The gun has not been modified since. I hope that this helps some. All the Best, Slate

It may be a Greener Ejector Model No. 1, a boxlock gun built with Greener-patent Self-acting Ejectors. These guns are often called G guns.

This is a Greener Ejector Model No. 1:

According to the Greener book, Greener also made a grade of boxlocks called Monarchs. These guns were made with Anson & Deeley and Facile Princeps actions and all them had their ejector work in the forend (unlike Greeners with Self-Acting or Unique Ejectors).

From 1893-1903, Monarchs made on A & D actions came in 4 grades, Monarch G1 to Monarch G4.

Here's a Monarch built on the Facile Princeps action:

It says Grade G1 on tang and looks like Monarch model. How G1 correlates to G-XX Greener guns, is it the best or mid gun?

Top grade, the finest grade of boxlock they made at the time. Although, presentation-grade Greeners were finished to a higher standard, like a Purdey Extra Finish or an H&H Modele Deluxe.
