Re: DW 5000 help
I'm not an expert, so don't quote me on this.
I have a DW5000. The '5002' moniker is simply the designation for the double version of the 5000. It looks a lot like my model - which would make it a 2000s-era model. Nothing in the photograph suggests to me that there is any discontinuity between your pedals - they look like they 'belong'. The earlier 5000 models have single chains and a more obvious waist on the footboard - they look a lot more like the Camco pedal that they were originally based upon. The 5000 series hasn't had a significant design change for years (since the 90s).
The fundamental question is: 'Does it work?' If it does - no problem!
