Is the 38mm the ctrs of the mounting plate (usually 32mm) or the two on the cup side (usually 45mm), also what diameter is the cup, 35mm is usual but it may be a mini hinge.
fraggle - try www.woodfit.com, they don't do Lama but can supply similar hinges with 26mm cup (I think maybe your existing one might be 26 & not 25mm dia).
