The 102 came with my 1950's pre-27 and I presume it's about the same vintage. As a 5" N-Frame I'm sure it would be difficult to preplace and they make a fine holster.
But I'd have a hard time paying more than $50 for a 4" K-frame 102, and $200 for an unlined custom sound very high to me? a Three Persons, El Paso Saddlery could be had for $75, lined!
