I have 4 Leo 1 projects in the works. One is back dating the Italeri A4 to an A3 . As near as I can tell I just need to replace the PERI scope with the older scope and add the PZB 200 night scope. Sounds like all the other mods were internal. Anybody happen to have the Italeri/ Revell PZB 200 and the scope (part 177 in Rev #03017, part 176 in Ita #374 and 6481) in the spares box? Thanks.
