Hiya lukky and thanks for your thread. Thats a nice rami you got there,congrats. I'm in arizona and wonder if you might elaborate on MD law. So having a concealed carry permit does not help you get your handgun on same day? Or is the collector paperwork another way to tax for those who prefer to ?
Interesting about your upside down letter Y on the frame, think the production year has been the only marks caught my interest. But try the search function here at the forum to. Google may turn up something. If ya want to dial the place that did the stamping, that would be the Czech proof house of the arms and ammunition,you can email them at info@cuzzs.cz or 420 284 081 826 (firearms and ammunition dept)
420 284 081 840 (deputy director)
420 284 081 821 (switchboard,firearms entry)
or if ya need to fax a pix 420 284 081 837 (registry fax)
if in no hurry their site cuzzs.cz has a on line contact form you can use to send your question. Cheers. Be well.
