I bought this Lego set off the internet and I can’t figure out the set number. Can someone tell me the set number?
As @mindstormsboi pointed out, it's a modification of 60009-1 Helicopter Arrest
- 10218-1 Pet Shop
- 10232-1 Palace Cinema
- 10246-1 Detective's Office
- 10255-1 Assembly Square
- 10264-1 Corner Garage
- 41108-1 Heartlake Food Market
- 60009-1 Helicopter Arrest
- 60069-1 Swamp Police Station
- 60130-1 Prison Island
and that doesn't look exactly like any of them. But if you remove 60009's vehicles and pier and add a few bits, it's a good match.
I won't say never, but Lego doesn't often (that I know of) sell sets with treasure chests where the lid doesn't match the base. But @Zhaph - Ben Duguid noted that 60009 does.
