Per another thread here, any regular sewing machine needle can be put in the chuck. Besides being smaller, it will also be shorter, but not a problem.
I was recently to an independent and very busy fabric store with vast stock, and picked up a 5 pack of Schmetz 90/14 jeans / denim sewing machine needles for $3.00. (Plainly a mis-mark, as most needles there were $5 / pack. But the low price sticker didn't stand out among other labels on products from West Germany, yes, stickered by a clerk there twenty years ago.
I doubt JoAnns carries NOS like Stitch 'N Sew (Lakewood, NJ). How could they if they haven't been around for 60 years?
Lots of previous generations must have had sewing awls as part of the home kit. There's no shortage of them on ebay, still in the box.
