OK I have broken the riser arm on the forward hatch of my 1985 H34. :cry: I can read that it is a Bomar hatch but have no idea what model. Going to the Bomar site it looks like a 100 cast series but hard to tell for sure from the pic and I hate to order not knowing if it is the correct riser. Would not surprise me if, like most everything else they no longer make it. Wondering if anyone has had to replace theirs and what they found. Sorry guys I looked at the store but you don't list anything for the H34 hatch riser.
