we had some chats on Sowerby Rds. Nos. 282663/64 some few years back - see link -
https://www.glassmessages.com/index.php/topic,54363.msg308189.html#msg308189so really nothing new with this post - it was just that I found this one today and thought it might vaguely be of interest as not sure if we've had this shape previously. Thompson shows an attractive example in clear blue - p. 84 and a toast rack in clear on p. 76, and the decorative design appears on one or two other pieces. TNA copy of the factory drawing appears to show this Reg. design on what looks like a circular plate, but certainly this granular frosted effect looks to have been popular. These were the only two Regs. on this date.
