I am offered to buy a team issued Steelers helmet supposively owned by a former equipment guy & the logo decal is like the current glossy thicker ones compared to the thin ones from back in the day & the word Steelers has the little spaces between the S's & the E's just like the logo you will see in the end zone & T shirts ect.I was wanting to know around the vicinity when the Steelers quit using the paper thin logo on the helmets & was the word "Steelers" ever stenciled on the logo with the little spaces between the S's & the E's on the helmet logo for a season or two? I looked on wekipedia & it said they experimented in the 80's with the logo & then changed it back to a solid Steelers writing on the logo.HELP!
