Thread: Gillette DE I found in a thrift store

I, this is my first post. I found a Gillette DE razor in a thrift shop and picked it up for 3 euro. I already use a nice heavy Merkur DE and am buying a straight edge soon (probably a vintage one). I'm wondering if anyone can tell me what this razor is worth? I'm debating whether I should sell it or use it as a backup/travel razor (since it's lighter than my Merkur). It came in an original (?) plastic case, is a 3 piece, and is stamped on the underside of the...not sure of the right term, the middle piece, with Gillette in a diamond and "Made in England". There was even an old Wilkinson sword DE razor in the case, also marked "made in england". Here are some pics, one with the Merkur for comparison (sorry about the quality). Any information would be appreciated.

Thanks
