We have recently acquired an H&A .32 XL Centre fire Revolver and would like more information about it if possible. Top of barrel says PAT. MAR. 28, 71 JAN. 5, 86 X.L. DOUBLE ACTION .32 CENTRE FIRE and it has a folding hammer. It's nickel plated. The only corresponding numbers we have found on it that may be the serial number is 188. The locations we found this number at is under the grip, on the cylinder and on the top strap. So far the info. I have found dates it to 1866 to 1899. I would like something more precise and an estimated value please. Also, any other info. about it would be great. Thanks in advance.
