...I apologize for what appears in retrospect to be a maddeningly vague description of what I was looking for...I originally posted from work today - and now that I’m back home, looking at the bottle I’m trying to match precisely, it’s dawning on me that there are many slightly different versions of these bottles 😬
...this might not be quite as simple as I thought

...attached are pics of MY bottle, the one I’m trying to match...it measures just a hair under 6 7/16” tall, and the base of the bottle is just a hair under 1 7/16” in diameter...there is a t-i-n-y number ‘6’ embossed on the neck of the bottle, above the shoulder and below the lip...might be a mould number, or a number indicating where that sample was to be positioned in a display...
...thanks, Mike - but it appears the lip on my bottle is a little thinner than the one you posted...
...I realize I’m being somewhat picky, but these bottles are going to be displayed right along side of three identical bottles, and any differences will stand out...
