Finally riding a big boys bike
Hi Alvin @altapat
MG87407 is, as you think, a 1942 frame, possibly J7, 8 or 9 (July to Sept 1942). Originially it would have had the Coffin style chainring, and an L2 or L3 (Quarter 2 or 3 1942) dated Morrow . It is one of the earliest of the straight bar frames.
MG87566 of @moparwrecker72 is the closest survivor I have recorded:
G-519 Westfield Columbia finally done | Military Bicycles
Hi Wanted to share pictures of my military Columbia. Serial number MG87566. I purchased this bicycle at a garage sale in the middle of Nebraska. It was in pretty rough shape. I would like to thank Howie the Bikeman and Alan from Bergerwerke bicycles for parts. Would also like to thank Johan...thecabe.com
Thanks again for your help.
Best Regards,
Adrian
Thanks Adrian for the details you provided. Now the search for the elusive hubs begins.
