Chubbo,
Maybe I'm one of those to blame for you wanting to shoot that revolver

I shoot mine & love developing new loads for them. You may have seen the links to my "penetration tests," etc. from this spring.
I won't try to judge the condition of the gun, but ammo is just simply not a problem if you reload. Heck, I'm keeping some of my .38 S&W's and selling a bunch of others, and I have hundreds of once-fired Starline cases you could talk me out of & that would probably keep you shooting for a very long time. Don't know if Starline currently has them in stock or not--worth checking. Also Remington and Magtech are often available from MidwayUSA.
Speer 13 specifically states that they used regular .358 bullets to work up their loads, so bullets generally aren't a problem for practical shooting. If the groove diameter of your revolver is too large for that solution, you can buy cast bullets of the correct size or cast your own. I started casting just last year, and have made up tons (OK, OK, quite a few pounds

of bullets. You could talk me out of a bunch. Better yet, buy an inexpensive Lee mold and make your own. Don't know if you cast or not; I'm 51 and just started a year ago, and mine are just fine. The real pros can do some black magic with casting, but if you're smart enough to reload, you're smart enough to do basic casting & get satisfactory results. Some of my loads, with my own cast bullets, have less than 10 fps standard deviation; one 215g bullet is UNDER 5 FPS SD. Believe me, I'm NOT a magician.
With brass and bullets, common pistol powders and SP primers, just buy a set of $26 Lee dies from MidwayUSA and you're in business. Easy to reload--not a tricky cartridge.
For my solid-framed guns, I load practice ammo that's a factory duplication load with a 140g Lee SWC I cast. I also cast several other bullets, such as 200g and 215g heavyweights, plus a Lee .358-158. They all do fine. For yours, I'd just load down the factory duplication load a bit. If you get a solid-framed gun, heck, you can shoot 200g bullets that duplicate the original British Army cartridge of the early 1930s, and it's no slouch in the "heavy & slow" category.
If you were trying to select a target revolver, it wouldn't be a great caliber to select because of past issues with different groove diameters in different guns. But as functional revolvers for close-range work, even lemon-squeezer ranges, this is NOT a problem. It's also no problem for the reloader and/or caster, if you're setting up for one gun. You don't have to worry about interchangeability then. You're micro, not macro, and I believe most complaints about the .38 S&W are macro.
Believe me, I'm not trying to sell you a thing, I just think that the .38 S&W has an undeservedly bad reputation for all the wrong reasons. It's ONLY a problem for someone who doesn't reload. It was a highly successful cartridge "back in the day" for a reason--actually, for several reasons--and for most of us, those reasons still apply today. Home defense? Self defense? With a solid-frame revolver, this isn't a problem either, if you believe that standard-pressure .38 SPL ammo is acceptable. Without getting radical on your loads, you can approach low-end .38 SPL ballistics. If you think there's something to heavy bullet solutions, you can cast 'em up, flatten the noses, and create a 200g near-wadcutter at 625-650 fps, and watch it shoot thru 6 jugs of water from a 2" barrel. . .If 36" of water is generally equivalent to 18" in ballistic gel, and all with a .280 meplat, well, it can shake 'em up, I reckon!
Happy shooting! Sorry for the wild-eyed rant
