RD 194040 was registered by Schindler & Co. on 17 June 1892.
(They also registered RD 194041 on the same date, but I've no idea what that looks like).
Schindler & Co. registered some 61 designs between 1890 & 1913, and the firm and some of their registered designed have been discussed several times on the GMB, particularly
http://www.glassmessages.com/index.php/topic,57935.0.htmlIt would appear likely that the actual glassware was manufactured by Schindler & Co. in Jablonec, Czechoslovakia.
RD 194040 is their earliest design registration that I come across so far, and I don’t know of any other image of a piece from the design.
Could I have your permission to add copies of your images to the GMB RD database, please, Angela? - with due credit, of course.
