Distributor wrench

Out here in N.J. visiting my folks for a week. Helped my dad do some rear axle work on his 1930 model A. So he hands me this. A 1/2" distributor wrench. What a handy item for me to have. Everything i used to work on mopar wise was big blocks and 2.2 turbos. A regular 1/2" wrench always sufficed for those. Now that i am doing small blocks I really need this tool.

Thanks
Dad !!!
