I have been searching the internet companys and I have been
"stumped" to find a maker of a hand or press halmark for myself.
Microstamp in Pasadena, CA has been mentioned several times on this
list. I visited their shop and was impressed with the variety of
what they can do, literally anything you need. But I found their
prices for a simple text stamp were a little steep.
My choice was Harper Mfg Co. in Las Vegas, NV. They have stock
stamps and can do special orders of lettering and artwork. Best to
call them for a catalog 800 776-8407.
About two years ago I selected a four letter stamp about 1mm high
which used one of their standard fonts. Cost was around $45 and
delivery was about 10 days.
