Featured Chartreuse Glass Bowl

Hello Board Friends! I bought this little bowl at auction today thinking it might be Duncan Miller's chartreuse but so far haven't been able to turn up the shape in either my books or online. It measures about 5" across including the handle and stands about 3 1/8" tall at the handle. It has a polished bottom and gives a strong glow under black light. Any help on the who, what, when, where would be much appreciated. Thank you!
Don

 

For some reason my initial reaction is Duncan
& M but no more than that.

 

Either D & M, or Tiffin after they bought the Duncan molds.

 

Reminds me of the Steuben Snail Handled Bowl. The handle looks a bit different, but I think whoever made it was copying Steuben. Don't know if steuben made that color. But you might look carefully for a mark just in case.

edit. I Think the bottom of your bowl looks to polished to be DM. Steuben marks can be tricky to find. I had a snail handled bowl I KNEW was steuben, but it took me 2 days to finally find the mark.

 

I think one inspired the other but to me the handle infill and shape of the bowl are not the same.

 

Thank you all for your opinions. I'll search for a Steuben mark but it seems unlikely - the quality just isn't there. There are tiny bubbles sprinkled throughout the bowl. Not a ton of them and not large ones but I don't expect to see bubbles on Steuben. I didn't check my Tiffin books but will do so now to see if I can find the shape. Your help and time is much appreciated.
