you would have to find out who the importer is.
id assume probably Korth.
if you go to your LGS and they carry Henry you could ask them who they get theirs from.
it does not matter if its a big or small LGS, as long as they carry Henry than they can get it from the distributor.
you could ask them who their distributor or get them to call the distributor and inquire for you.
i would assume that they would probably not be to receptive about a one off for importing.
if you absolutely have to have one id look at irunguns or prophet.
with irunguns you can order from states and have it sent to their US store down in Arizona(?) and then imported from there.
will cost ya an extra $200.
my dad did that with a one off gun he had to have.
he ordered straight from the company and had it sent to irungunz US store and then imported from there.
was actually pretty easy.
just took a month or 2.
