Dear Andrea,

A company called R.A. Lamb here in the U.K. sell the glass staining troughs
you are looking for.
The last price I had for them was £6.50 each or £6.25 if you purchase 10 or
more.
The racks to fit these troughs hold 25 slides and can also be purchased at
£15.85 each.
The cat. no. for the troughs is E/105 and E/102 for the racks.
The address of the company is:-

R.A. Lamb,
Units 4&5 Parkview Industrial estate,
Alder Close,
Lottbridge Drove,
Eastbourne,
East Sussex,

England.
