50s bike, looks like it has the 'bullseye' badge, with Rollfast across the rings. That would suggest mid 50s. A lot of these have the year stamped in reverse on the bottom bracket. It's a separate code from the serial #, something like "65 EH" would be a 1956. That's about as much as one can decode these Snyder built bikes, and the reverse year isn't 100 % proven, or known how late they used that system. -Adam
