Hi Dickim,
I bought through eBay UK, the supplier is royalspareparts.
The guy also gave me his business card, & operates Sparezo,
www.sparezo.com, from New Delhi. I found the eBay site much cheaper to buy through. Delivery was 8 days New Delhi to New Zealand which quite honestly shocked me. I'm used to waiting weeks for anything out of India.
I had considered just buying the frames (as they are available separately) and bolting a pair of old army ammo cases to them.
