VTG SWAGE SLITTED BLOCK TINSMITH BLACKSMITH SHAPING FORM RAILROAD TOOL IR5 7041

Front reads: IR5 7041(has IR symbol). I am unsure of the exact use for this interesting early swage block?. Swage is in good pre-owned condition. Stay tuned. Check back often! Block is 4" long x 3 1/4" wide x 2 3/8" high.
