Yes. they are proper shortscale. You can get the necks from the company, too. They are pretty good, but another Czech manufacturer, Fokus, makes them with proper fender headstocks.
No, they don't, but maybe if you wanted one you can get it mailed to my adress and we can maybe meet or something. But the fact mine has got a great neck is a hit/miss situation i think, so i wouldn't really ever order one without expecting it to be a good looking shit guitar.
EDIT. Sent them an e-mail about stocking theese into any shop in Prague, so let's wait for the reply.
This store stocks some, but you will have to ask them about the stangs... they are very unpopular guitars in the Czech Republic. Everybody, including punk and metal dudes just play teles, les pauls, strats or some ibanez 8 string things, no other guitar. Even the biggest stores usually have like one jazzmaster and one mustang on display in the middle of thousands of strats and LPs hanging off the walls everywhere.
