Amber Glass Flask

Any idea of the maker?
Thanks

 

Are my eyes playing tricks on me or . . . are those some raised letters running vertically on the "front?" of the flask/bottle????

Looks like maybe an "H" or an "M" for the first letter with maybe five letters following in a downward direction toward the bottom of the flask/bottle..

 

No letters, that's a production flaw.

 

Can someone tell if the piece is mold blown or machine made?
The side seams start from the very bottom, then disappear and then again seams but not that straight and neat. Seems like there are some on the finish and the top but can't tell for sure.
