I bought a frame, forks,painted guard labeled Cruiser,handlebar clamp and crank assembly badged Firestone with a Monark decal on the seatpost . I found a picture on Google of what appears to be an identical bike but it has different style chrome chain guard and fenders. I also found a picture of a girls with same paint scheme and chain guard but painted fenders. The serial number on mine looks to be (A or 4) 1020395 and the model 18008A57. Wondering what year it might be.
