I believe what we have here is a failure to identify, "H-B....................Unknown" From.
That second one is another stumper. Good shards! What kinda context or approximate era are they from? Bottlemarks-R-Us had this:
"H.......................Might have been used by several glass companies: Possibilities include Hemingray Glass Company, Muncie, IN [See Hemingray]; H.J.Heinz Glass Company, Sharpsburg, PA (c.1893-1946); Hagerty's Glass Works, Brooklyn, NY, and probably others. An "H" could in some cases be only a mold identification letter or internal factory code. Holt Glass Works, West Berkeley, CA (1893-1906) is the source of various bottles with an "H", found primarily in the Western states. Holt-made bottles will have a number (with one, two, or three digits) accompanying the "H". In most cases, the number is reportedly found ABOVE the "H", although in some cases is may appear either below, or positioned to the right of the letter. Keep in mind that attribution of a bottle with an "H" mark to any definite glasshouse is often very uncertain. NOTE: Hand-blown aqua oval bottles with applied or tooled lips, used for Reuben P. Hall's "Hall's Hair Renewer", are found with just an "H" on the base, and in this case, the H presumably stands for "Hall". See next entry also.
H-28 (or w/other 2-digit number)....Hemingray Glass Company, Muncie, IN (used c. 1924-1935). Information proven to be correct from Hemingray historian/researcher Bob Stahr. However, this doesn't rule out the possibility that a mark similar to this one could be seen on products from other glass factories. Type of bottle, age, color, and other characteristics must be taken into account to decide if this would be a Hemingray product. NOTE: If the number consists of either one or three digits, it is not Hemingray. On Heinz bottles, a number (which may consist of one, two, or three digits) which accompanies an "H" on the base refers to a particular design or style of bottle made by Heinz, and is not Hemingray-related. Holt Glass Works, West Berkeley, CA also produced bottles with an "H" and a number, but these are usually found only on the West Coast. See "H" entry above." Again. The boldness of that 2nd H with what I'm taking to be an interspersed 33, makes me think you have gone 2 for 2 in the Unknown Department...
Your mission, should you choose to accept it, is...
