If you dont know the maker please use UNKNOWN (not Custom built) as a "maker".

If it is surely a homebrew set, please distinguish between HB-contempary for sets done in their times and HOMEBREW - New but not Replica and HOMEBREW-REPLIKA.

Please look up the possible models to load up your picture. Give all details about the set you have - there might be someone who can tell you more about your set. Your name is shown automatically - to members only.

Please make sure that your sets contain a visible stamp "Replica", done in a manner that tampering is hard to do. Unfortunately there are some replicas which are beeing sold as originals - like the De-Forest-Audion. Therefore it would be great if someone loads up pictures showing possible differences to originals ...
