Can anyone give me advice as to commercial jigs for making dovetails in wood as thin as 1/4". Most jigs seem to start at thicknesses in excess of 1/2".

For through dovetails, can you not cut two sides at once if they're that thin, or perhaps use a scrap backing piece to make up the thickness to the minimum?
Usually the problem is getting the capacity to handle thick enough timber.
its been discontinued but I use the trend dc400 jig
You can find used examples on ebay from time to time its really good at all different thicknesses and allows you to space dovetails as you wish and through or lapped DT's
Thanks for the info, but the DC400 and its supercedant will only cut on material 19mm and thicker – I need about 7mm upwards. Jewel box trays etc.

The Leigh ones will go down to 1/8" thick material and upto about 1.25" for through dovetails, see chart
Also take a look at the Gifkin Jigs, they will go down to 2mm but need a router tabel as you move the jig and work over the inverted tool, fixed spacing though.
