There are many period accessories available to suit the Iloca range of cameras. In general, older items such as flash units and tripods are good for display purposes, but are no longer practical for use. Virtually all of the early flash units use old style flash bulbs and many have battery types which are now obsolete. Similarly, many of the early tripods, although compact when folded away, tend to be less stable than their more modern counterparts.
So if function is important, you will be better served with more recent accessories. Most Iloca cameras include tripod sockets and PC flash contacts that are compatable with later equipment, and flash synchronisation on these cameras seems to work well with most electronic flash units.
Lens hoods, filters and shutter release cables are a different matter - suitable items from any era can be used.
For display purposes, however, nothing enhances these old cameras in the same way as some carefully chosen accessories from the right era.
