The R in a triangle was used by Reed Glass, Rochester, NY. They closed shop in the mid 50s. The # to the right of the triangle is the year, ie 43 means 1943.
Scott, your House Brothers line got me thinking. I have House/House Brothers bottles from Rochester, Lyons and Syracuse,NY. The Rochester bottle is embossed with House Bros and Qualtop Beverages. Qualtop lasted into the late 50's or early 60's but this bottle is probably from the early 1900's...
Recently added a 10 ounce TOPFLITE bottle from Leonard's Beverages, Rochester, NY, that has an acl that is brown and white with a jet on the label. I've seen blue & white and red & white acl and have heard of a green & white acl. Has anyone seen or heard of a green or brown version like this?
