Thanks for the response. William Hurst has responded quite thoroughly. One item I omitted was that the bottle's bottom had cast in glass, "10 HAIG & HAIG EDINBURGH SCOTLAND" which may date the bottle prior to 1950 as William notes, "1950 - Haig & Haig begins moving facilities from Edinburgh to Markinch. (1951 bottles marked M&E)". But he and I still need to correspond about that. As "1947 - Renfield Importers acquires exclusive distrbution agreement from Haig & Haig." We will see.
