At the La Gleize show this weekend there were collectors with the theory that the new Tchech haul are actually papiergarn covers for Glass bottles, and they are being sold with metal bottles.
A couple of my thoughts to that...
1) I spoke to one of the sources at La Gleize this weekend, and saw some pics of the hoard... I have little doubt these were found under the circumstances he said... I cant "Know"... but I think...
2) Even if the Covers were made with glass bottles in mind.... if in the stores there were these covers, and no glass bottles... would they not have used them?
3) My pet theory, seeing the huge amount of different bottles kinds of metal bottles in the covers... some looking used... that these may actually have been in the local supply/Maintenance stores... exchanging damaged linen and cord covers for new Paper cloth ones. We all have cloth covered bottles that could really have used a new cover... so why not?
By belief is that these may have been made for Glass bottles, but from the information I saw at La Gleize, I think it certain that metal bottles were put in them back in 1918 for shortage of material reasons, or as replacement covers.
We are talking about a relatively large find... It is very unlikely that someone went around buying bottles, removing the covers they had, then putting on new ones...
