We have a very old silver umbrella that we think was made by Balcar but there are no markings on it. it is falling apart in so many different ways but we just can't do without the beautiful light it gives. The shaft and all the spines are metal. The outer fabric is gray and the inside is a matte silver, NOT glossy, spectral silver. Has anyone seen one of these or have one to sell? We use it on 1,000 watt hot lights so some of the newer umbrellas with plastic parts just melt immediately. Please help!!
