yes. so you have the middle of the three options I listed earlier... it has the raised letters 'oval roaster' on the top of the lid... and all of the other identifiers on the inside... there are some that say 'griswold #9 dutch oven oval roaster' all in raised letters on the top... that's what they refer to as 'fully marked'.
So to summarize, yours says 'oval roaster' in raised letters on top.
then the usual griswold logo and erie, pa. usa and number on the inside of the lid... then the bottom of the roaster pan itself should have a big block griswold logo, the number and more writing.
so that puts yours as being made between 1934-1940's.
the blue book lists the price range as 300-400 for the roaster and 125 for the trivet... but keep in mind the prices in the blue book are 6-7 years old... I'd say you're still in the 500-800 range for the full set given the current prices.
post pics when you get a chance, I'm sure there are a lot of people on here who would love to see it.
