Heya Leth,
i ordered mine, and got it within 2 months after order. The issue is, that Jay (or Jason if you prefer) has more or less "cottage" industry so to speak in the small scale, and frets are done in batches.
what i did, was googled his adress and telephone number that is located on modelbrass page, 23300 Broadwood Dr. Elkhart, IN 46514, USA (574) 361-9868, and got this:
http://www.3rdgendecals.com/i used the contact form and email provided there (Email tab) , and luckily the guy is the same, which can i confirm. Simply write him to jay@3rdgendecals.com or use the contact form, and he should get back to you in a day. The longest what i waited was 3 days, shortest 5 hours. Just make sure you do contact him once or twice a week to check up the status, otherwise it just might get forgotten (we all do forget about things if not reminded)
and yes, modelbrass.com email domains are down, so only way to get him is the telephone (not confirmed), or the 3rdgendecals email
Hope this helps,
regards,
Marko
