Hi Dick,
I am currently trying to establish a register for the Royal Enfield WD/CO, so have quite a bit of knowledge about these frames.
Number 7186 has been issued to both the WD/C and the WD/CO models (in 1940 and 1944 respectively). The WD/C has the typical WD/C frame, whereas the WD/CO with that frame number would have had the so called type 2 frame.
If you send me a picture of your frame, it shouldn’t be too difficult to find out which model it is. My email address is: jan.vandevelde@vac-machines.be
If anybody else who’s reading this would also have a WD/CO and would like to have it in the register, please send me a picture of it plus details such as frame number, engine number, other stampings on the engine, despatch date for those who have a dating certificate from the Royal Enfield Owners Club, … Thank you very much in advance for your appreciated help!
All the best,
REgards,
Jan
