Flint glass sugar (I presume) 4 1/4" high with rim diameter of 6", the glass is quite thick approx 1/4" and weighs 800gms.
Pressed glass with double bullseye with triple arch and fans and with sawtooth rim.
Underneath has a number, very faint and uneven 3087 I think but doesn't say RD or REG No.
Not sure if this is English or not?
Hoping someone recognizes the pattern
