Click on my "verified user name". Mine is a 1980 Tomos Bullet. Vin tag should be on the fame up near the seat. Solid bike, 2 speed automatic. Yours looks to be a late 70's early 80's A-3 I would assume. I paid 500 for mine and worth every penny. Hope that helps. Click on the photo tag up top and scroll down to tomos and find a similar bike I am sure there is one posted.
