H&A made several Forehand top-break models in .22, .32 S&W and .38 S&W calibers; the latter caliber used a larger frame. They were made in hammer, hammerless (concealed hammer), bobbed hammer, and folding hammer styles. .22 models were 7-shot, while the .32 and .38 revolvers were 5-shot.
Value is not high, topping out at around $200 even in new or near new condition. The H&A guns are better made than many other breaktops of the period, but before shooting, remember that parts are no longer available if anything breaks.
