I need your help (and I don't have the serial no. yet, in transit) for an approximate age, and anything else you can tell me about this .38. you guys are great, any help appreciated. Thanks, six

Also, are the grips appropriate? six

Another question; will S&W reblue an older revolver like this? six

Looks like a pre-war .38 M&P 1905 model, made until WWII. Serial number will help to pin down a date of manufacture.
The grips are from a post-war period.
I don't think the S&W factory will work on guns this old, but you can call them at 1-800-331-0852 and ask.

Need the serial number before we can give you much information.

No, the grips aren't right. They're post-war. the gun appears to be pre-war.

AFAIK S&W won't work on anything pre-war.

Thanks so much, guys, we'll get the serial number and pin it down. six
