As X-ray said, some of us still use them.
With older cameras you can sync focal plane provided you use M setting and fast shutter speeds: it's the opposite to electronic flash. I have a nifty adaptable reflector that takes all types except the big screw in ones.
There are websites that specialise in selling flashbulbs. If you have lots (hundreds) they may be worth contacting. Otherwise use the classifieds or eBay.
