The 3/4 size was and still largely is what made it popular. It's easy to underestimate a 99, it sews just about anything like the full size models. My 99 runs lighter than my 201s for some reason. It sews fine, and when cleaned, oiled and sorted out it's a smooth running machine. The decals looks very nice, and probably will shine up very well. It's easy to clean, oil and thread. There's no reverse on the old 99s or 66, they have a stitch length turn knob. Later version have a stitch length lever with back tack.
