A&L is primarily a manufacturer of high quality reproduction Model A parts. They supply lots of parts to Snyder's and Bratton's. They are not really set up for retail.
They are located in North Central Connecticut and they welcome visitors if you call ahead.
They do accept phone orders. Theymake many high quality parts. as mentioned 30-31 brake light switches, also Sparton horns with correct month data plates,and the best copper manifold gaskets that I have found-they do not squish out.
