Metal chess pieces

Greetings.  By way of introduction, I am a first time poster who has enjoyed the threads in this topic.  Pretty simple tastes in chess equipment: Drueke boards and wooden Staunton-style pieces (plus my old favorite, an APF Rolland no. 535 in use since c. 1980).

Here's my question: I acquired a 15" x 15" Drueke that included a metal chess set (nickel and brass?).  The seller insisted the chess pieces were a Drueke set, but I have never seen or read about Drueke selling metal pieces, nor is research on-line yielding any evidence.  Here's a shot of some of the pieces.

 If this is not the appropriate site, any suggestions as to where I can turn would be helpful.  Thanks.

it sometimes takes awhile for images to upload.....try again and wait a few minutes if necessary

Also chess.com has a probationary period for new members before they are allowed to post pictures, videos and links to their comments as a deterrent to spammers. 

Thanks for the insight.

Found this thread while looking for info on metal chess sets. The image icon shows broken link. Maybe, uploading again would help if the issue isn't solved yet.
