Well, picked it up yesterday. It is an L54 and has the 7300 panloc rails. Rather different than the rails from the late 60s and early 70s. A blemish on the front high enough so the front panel will not hide it and some minor scratching on one side. But for $100US and no shipping I can live with it. The seller also showed me a 6100 he picked up and has a trade offer on. He will call me if the deal falls through. It has some (3) bubbles forming on the lower portion of the glass and includes a slant leg L-52. Since I don't need the 52 as I have a new in box spare, I'll try to cut a deal with his for the amps sans the 52. Nice reseller but he is a bit nervous about shipping so he's wiling to deal if not shipping involved.
